Short-term efficacy and safety analysis of TACE combined with TKI and PD-1 inhibitors in the treatment of initially unresectable hepatocellular carcinoma / 中华肝胆外科杂志

Objective:To evaluate the efficacy and safety of transhepatic arterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKI) and programmed death-1 (PD-1) inhibitors in the treatment of patients with initially unresectable hepatocellular carcinoma.Methods:The clinical data of 42 patients with initially unresectable hepatocellular carcinoma who were admitted to the Department of Hepatobiliary and Pancreatic Surgery of the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were included. There were 31 males and 11 females, with a median age of 56 years old (range, 45-72 years old). All patients received TACE+ TKI+ PD-1 inhibitor combined treatment. The systemic treatment cycles were calculated by the regimen of immunotherapy. The timing of local treatment depends on tumor size, blood supply and treatment response. Patients were followed up through hospitalization, outpatient visits and telephone review. The Kaplan-Meier curves were obtained for survival analysis.Results:The dosing cycle to achieve optimal imaging response in the patients was 4 (3, 7) [ M( Q1, Q3)], with a systemic treatment time of 141 (65, 194) d [ M( Q1, Q3)] and 2 (1, 3) times [ M( Q1, Q3)] of local treatments. All patients were evaluated by modified response evaluation criteria in solid tumors criteria after treatment, including nine patients with complete response (CR), 21 with partial response, eight with stable disease, and four with progressive disease. Objective response rate and disease control rate were 71.4% (30/42) and 90.5% (38/42), respectively. Treatment-related adverse reactions occurred in 85.7% (36/42) of patients and grade Ⅲ or Ⅳ adverse reactions occurred in 16.7% (7/42). There was no level Ⅳ adverse reactions. All adverse reactions were controlled after dose reduction and symptomatic treatment. Thirteen patients (31.0%, 13/42) redeemed resectable after treatment and underwent radical surgery. Seven patients had pathological CR after surgery. In two patients, the pathological residual cancer tissue was less than 10%. The cumulative overall survival rates of the 42 patients at 6 months, 1 year, 1.5 years after treatment were 100%, 91.7%, and 65.0%, respectively. The postoperative 1-year survival rate of patients undergoing surgery after successful conversion was 83.3%. Conclusion:This study preliminarily showed the safety and efficacy of TACE, TKI, and PD-1 inhibitor combined therapy in patients with initially unresectable hepatocellular carcinoma.

Conversion therapy strategies for hepatocellular carcinoma in the era of targeted therapy combined with immunotherapy / 中华消化外科杂志

Hepatocellular carcinoma (HCC) has an insidious onset, and most HCC patients have reached the intermediate-advanced stage when they were diagnosed, which lead to missing the opportunity for radical treatment and suffering a poor prognosis. Conversion therapy is an important tool to improve the prognosis of patients with unresectable HCC by creating resectable opportunities. With the new targeted agents, anti-vascular agents, immune agents and multi-dimensional treatment regimens bringing high objective response rate and long duration of remission in HCC treatment, conversion therapy has emerged as a hot spot in the clinical research of HCC. In the era of targeted therapy combined with immunotherapy, the connotation of conversion therapy for HCC continues to expand, with strategies constantly being updated. As such, conversion therapy for HCC has entered a rapid development period, but still faces many challenges. Combined with clinical experience and the latest research progress, based on the efficacy of systematic therapy with targeted combined immunotherapy as the core and combined local therapy in advanced HCC, the authors summarize the definition and expansion of conversion therapy and the conversion therapy strategies in oncology.

Clinical effect of different plastic biliary stent indwelling methods on managing obstructive jaundice in unresectable hilar cholangiocarcinoma / 中华消化内镜杂志

Objective:To compare the clinical effect of three indwelling methods of plastic biliary stent on relieving obstructive jaundice caused by unresectable hilar cholangiocarcinoma.Methods:A retrospective study was performed on data of 61 patients with obstructive jaundice caused by unresectable hilar cholangiocarcinoma from April 2014 to December 2020 in Cancer Hospital, Chinese Academy of Medical Sciences. Plastic biliary stent placement was used to relieve jaundice, including 18 cases of intragastric indwelling at the end of biliary stent, 31 cases of duodenal papilla indwelling at the end of biliary stent, and 12 cases of horizontal portion of duodenum indwelling at the end of biliary stent. Incidence of fever within 2 weeks, perioperative mortality, 90-day obstruction rate, and median stent patency period were followed up and the results were analyzed.Results:The incidence of fever within 2 weeks of the three groups were significantly different [66.7% (12/18), 58.1% (18/31) and 16.7% (2/12), χ2=7.30, P=0.026]. There were no statistically differences in the perioperative mortality [0 (0/16), 3.2% (1/31) and 0 (0/10), χ2=1.09, P=1.000], 90-day obstruction rate [52.9% (9/17), 48.3% (14/29) and 40.0% (4/10), χ2=1.91, P=0.589], or median stent patency period (66.0 d, 91.5 d and 94.0 d, Z=4.96, P=0.084) among three groups. Conclusion:Patients with biliary plastic stents with ends placed at the horizontal portion of the duodenum show lower incidence of fever within two weeks after implantation, and similar median stent patency period, 90-day obstruction rate and perioperative mortality compared with intragastric indwelling and duodenal papilla indwelling groups. Therefore, biliary plastic stents with ends placed at the horizontal portion of the duodenum should be recommended as the preferred procedure.

Prognostic factors affecting the success of conversion chemotherapy in patients with unresectable liver metastases from initially colorectal cancer / 中华胃肠外科杂志

Objective: To investigate the factors affecting the success of conversion therapy in patients with initially unresectable colorectal cancer liver metastases (CRLM) in order to provide evidence-based medical evidence for formulating individualized treatment strategies for patients. Methods: A retrospective case-control study was used in this study. Clinical data of 232 patients with initially unresectable CRLM receiving first-line systemic treatment in Sun Yat-sen University Cancer Center from January 2013 to January 2020 were collected, including 98 patients of successful conversion and 134 patients of failed conversion as control. Conversion therapy scheme: 38 patients received FOLFOXIRI regimen chemotherapy (irinotecan, oxaliplatin, calcium folinate and fluorouracil), 152 patients received FOLFOX regimen (oxaliplatin, calcium folinate and fluorouracil), 19 patients received FOLRIRI regimen (irinotecan, calcium folinate and fluorouracil), 23 patients received systemic chemotherapy combined with fluorouridine hepatic artery infusion chemotherapy; 168 patients received targeted therapy, including 68 of bevacizumab and 100 of cetuximab. Logistics analysis was used to compare the factors affecting the success of conversion therapy. The Kaplan-Meier method was used to calculate progression-free survival (PFS), and the Log-rank test was used for survival comparison. Results: Among 232 patients, 98 patients had successful conversions and 134 patients had failed conversions with a successful conversion rate of 42.2%, meanwhile 30 patients underwent simple hepatectomy and 68 underwent hepatectomy combined with intraoperative radiofrequency ablation. After first-line chemotherapy, 111 patients (47.8%) were partial remission, 57 patients (24.6%) were stable disease, and 64 patients (27.6%) were progression disease. During the median follow-up of 18.8 (1.0-87.9) months, 148 patients were dead or with tumor progression. The median PFS time of patients with successful conversion was longer than that of patients with failed conversion (31.0 months vs. 9.9 months, P<0.001). Univariate analysis found that the bilobar distribution of liver tumors (P=0.003), elevated baseline carcinoembryonic antigen (CEA) levels (P=0.024), tumor invasion of the portal vein (P=0.001), number of metastatic tumor>8 (P<0.001), non-FOLFOXIRI (P=0.005), and no targeted therapy (P=0.038) were high risk factors for the failed conversion therapy. The results of multivariate logistics analysis indicated that the number of metastatic tumor >8 (OR=2.422, 95%CI: 1.291-4.544, P=0.006), portal vein invasion (OR=2.727, 95%CI: 1.237-4.170, P=0.008) were the independent risk factors for failed conversion therapy, while FOLFOXIRI regimen (OR=0.300, 95%CI: 0.135-0.666, P=0.003) and targeted drugs (OR=0.411, 95%CI: 0.209-0.809, P=0.010) were independent protective factors for successful conversion therapy. Conclusions: The number of metastatic tumor and portal vein invasion are key factors that affect the outcomes of conversion therapy for initially unresectable CRLM. If a patient can tolerate chemotherapy, a combination program of three-drug and targeted therapy is preferred for the active conversion therapy.

Advances in therapies for unresectable hilar cholangiocarcinoma / 国际外科学杂志

Hilar cholangiocarcinoma is the most common malignant tumor of the biliary tract. Surgical resection is the only radical treatment method at present. However, due to its insidious onset and high degree of malignancy, it is usually in the middle or late stage when first diagnosed, most patients have lost the chance of radical surgery and have a very poor prognosis. In recent years, with the continuous progress of medical technology, the optimization and different combination of treatment methods such as chemotherapy, radiotherapy, biliary drainage, photodynamic therapy, nano-knife ablation, intraluminal radiofrequency ablation, liver transplantation, targeted therapy and immunotherapy has significantly improved the prognosis of patients with unresectable hilar cholangiocarcinoma. Chemotherapy, radiotherapy, photodynamic therapy and intraluminal radiofrequency ablation on the basis of biliary drainage can prolong the time of biliary patency. Nano-knife ablation can maximize the elimination of tumor cells on the premise of protecting the structure of the ducts. Liver transplantation offers a possibly curative opportunity for patients with unresectable hilar cholangiocarcinoma. Targeted therapy and immunotherapy provide a breakthrough point for precision therapy and individualized therapy. Based on the literature and the clinical experience of our team, this paper discussed the therapeutic approaches for unresectable hilar cholangiocarcinoma and encountered problems, so as to provide reference for clinical treatment and related research.

Computed tomography-guided iodine-125 brachytherapy for unresectable hepatocellular carcinoma

Purpose: This study aimed to retrospectively assess the outcome of interstitial iodine-125 brachytherapy for unresectable hepatocellular carcinoma (HCC). Materials and Methods: Between February 2013 and March 2019, 57 patients with 108 unresectable HCC lesions treated with computed tomography (CT)-guided iodine-125 seed brachytherapy were retrospectively analyzed. The primary endpoint was overall survival (OS). The secondary endpoints included local tumor control and progression-free survival (PFS). Potential factors associated with OS were assessed. Results: The mean follow-up duration was 24.3 ± 15.6 months (median, 20.5 months; range, 3.9–66.8 months). The median OS time was 23.6 months (95% confidence interval [CI], 18.4–28.8 months). The 1-, 2-, and 3-year actuarial OS rates were 80.0%, 46.1%, and 24.3%, respectively. The median PFS time was 12 months (95% CI, 9.9–14.5 months). The 1- and 2-year actuarial PFS rates were 50% and 20.1%, respectively. Local progression was noted in 11 (11.3%) of 108 lesions with mean local control time of 20.5 ± 8.8 months. The 1- and 2-year local control rates were 96.5% and 88.8%, respectively. Barcelona clinic liver cancer stage and Child–Pugh score were independent risk factors affecting the prognosis (hazard ratio [HR] = 0.330 [95% CI, 0.128–0.853] and HR = 0.303 [95% CI, 0.151–0.610], respectively). Hepatic artery pseudoaneurysm was found in 1 (1.8%) patient with lesion located in the porta hepatis. No other major complications developed during follow-up. Conclusion: CT-guided iodine-125 brachytherapy may be an effective and safe alternative with promising survival and increased local control rate in unresectable HCC treatment

Role of stereotactic body radiation therapy in liver metastasis: A pilot study from tertiary cancer institute in India

Purpose: This trial studies the feasibility and potential utility of stereotactic body radiation therapy in patients with unresectable liver metastasis. Aims: (1) The aim of this study is to assess the local response of the liver lesions poststereotactic body radiation therapy regarding number and size of lesions and (2) to evaluate the toxicity to organ (s) at risk. Materials and Methods: A total of 15 patients were enrolled in this study from November 2014 to October 2015. The inclusion criteria for this study were patients having 1–3 liver metastasis from any solid tumor except germ cell tumor or lymphoma with no evidence of progressive disease (PD) outside the liver. A planning four dimensional-computed tomography (CT) scan was taken. Planning target volume was generated by giving margin of 5 mm. Dose prescribed was 36 Gy in 3#. Response was defined by CT abdomen done at 3 and 6 months poststereotactic body radiation therapy as per RECIST guideline (v1.1). Results: At 3 months poststereotactic body radiation therapy, five patients had partial response, five patients had stable disease, and five patients had PD as per RECIST criteria. Out of 20 assessable lesions, 16 were controlled at 3 months poststereotactic body radiation therapy. The actuarial local control rate was 86% at 3 months and 77% at 6 months poststereotactic body radiation therapy. The median progression free survival was 7 months. Two patients experienced Grade 2 gastric toxicity and one patient experienced Grade 2 small bowel toxicity. No cases of radiation-induced liver disease were observed. Conclusions: This trial examines the feasibility of stereotactic body radiotherapy to liver metastasis in the Indian scenario. It shows excellent tolerability and is a safe therapeutic option for inoperable patients, showing good local control

Endoscopic Ultrasonography-Guided Gallbladder Drainage as a Treatment Option for Acute Cholecystitis after Metal Stent Placement in Malignant Biliary Strictures

BACKGROUND/AIMS: It is often difficult to manage acute cholecystitis after metal stent (MS) placement in unresectable malignant biliary strictures. The aim of this study was to evaluate the feasibility of endoscopic ultrasonography-guided gallbladder drainage (EUS-GBD) for acute cholecystitis. METHODS: The clinical outcomes of 10 patients who underwent EUS-GBD for acute cholecystitis after MS placement between January 2011 and August 2018 were retrospectively evaluated. The procedural outcomes of percutaneous transhepatic gallbladder drainage (PTGBD) with tube placement (n=11 cases) and aspiration (PTGBA) (n=27 cases) during the study period were evaluated as a reference. RESULTS: The technical success and clinical effectiveness rates of EUS-GBD were 90% (9/10) and 89% (8/9), respectively. Severe bile leakage that required surgical treatment occurred in one case. Acute cholecystitis recurred after stent dislocation in 38% (3/8) of the cases. Both PTGBD and PTGBA were technically successful in all cases without severe adverse events and clinically effective in 91% and 63% of the cases, respectively. CONCLUSIONS: EUS-GBD after MS placement was a feasible option for treating acute cholecystitis. However, it was a rescue technique following the established percutaneous intervention in the current setting because of the immature technical methodology, including dedicated devices, which need further development.

Neoadjuvant therapy for pancreatic cancer / 中华消化外科杂志

Pancreatic cancer has a extremely high malignancy,and simple surgical resection can not significantly improve the long-term survival rate of patients.Neoadjuvant therapy is the preoperative chemotherapy or combined chemo radiotherapy,which is used for downstaging tumors,eliminating subclinical metastases,transforming unresectable into resectable tumors,and improving the R0 resection rate of pancreatic cancer,thus ultimately improving the efficacy of pancreatic cancer.At present,neoadjuvant therapy has gradually become the mainstream treatment for locally advanced and borderline resectable pancreatic cancer.New adjuvant therapy for resectable pancreatic cancer has been supported by some high-quality clinical research data,which will become a hot topic in clinical research.The author believes that there will be more clinical research data to help individualized neoadjuvant treatment selection,accurate efficacy evaluation and prognosis judgement,and ultimately improve the efficacy of patients with pancreatic cancer.

Experience with non-cremophor-based paclitaxel-gemcitabine regimen in advanced pancreatic cancer: Results from a single tertiary cancer centre

Background & objectives: Gemcitabine combined with non-cremophor-based paclitaxel is one of the standards of care in advanced inoperable pancreatic cancer. This study was undertaken to retrospectively evaluate real world non-trial outcomes with this combination. Methods: Patients with histologically proven advanced inoperable pancreatic adenocarcinoma (PDAC), treated with non-cremophor-based paclitaxel-gemcitabine combination (PG) (gemcitabine-nanoxel or gemcitabine-abraxane) between January 2012 and June 2015, were retrospectively analyzed. Response assessment was done every 8-12 wk with computed tomography scan and responses were measured as per the Response Evaluation Criteria in Solid Tumours 1.1 criteria where feasible. Toxicity was recorded as per the Common Terminology Criteria for Adverse Events (CTCAE) v4 criteria. Progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan-Meier method. Results: A total of 78 patients with PDAC were treated with the combination. Of these, 83.3 per cent of patients had metastatic disease. The median number of chemotherapy cycles administered was three. The objective response rate for the whole group was 30.8 per cent. Grade III/IV toxicities were seen in 35.9 per cent of patients. Median PFS was 5.6 months and median OS was 11.6 months. Interpretation & conclusions: Non-cremophor-based paclitaxel in combination with gemcitabine appeared efficacious for advanced pancreatic cancers in routine clinical practice. Within the confines of a single-centre retrospective analysis, gemcitabine-nanoxel and gemcitabine-abraxane appeared to have similar efficacy and toxicity in advanced pancreatic cancers.

Safety and efficacy of nanoknife ablation for unresectable hilar cholangiocarcinoma / 中华肝胆外科杂志

Objective To evaluate the safety and curative effect of nanoknife ablation in the treatment of unresectable hilar cholangiocarcinoma.Methods 15 patients with unresectable hilar cholangiocarcinoma received nanoknife ablation treatment from March 2016 to May 2017.The clinical variables of the patients before and after operation were analyzed.Results The operations in all the patients carred out successfully.Cardiac arrhythmia occurred in some patients during the operation accidentally.The level of CA19-9 increased significantly on postoperative day 1,3 and then gradually decreased in 13 patients;one patient had no significant change of CA19-9,and the data for another patient was always in the normal range.The liver function of all patients gradually improved after operation,and the level of total bilirubin,AST and ALT showed a downward trend.The myocardial enzyme in all the patients increased on postoperative day 1,then returned to normal within the following 5 days.Postoperative complications included atrial fibrillation (1 case),upper gastrointestinal bleeding (1 case).The recanalization rates of the bile duct at 2 weeks,1 month,and 2 months after surgery were 66.6％,86.6％,and 93.3％,respectively.Conclusion Nanoknife ablation has superior safety,noteworthy efficacy and less complications in the treatment of the unresectable hilar cholangiocarcinoma in the short term.

Photodynamic therapy plus biliary stenting versus biliary stenting alone to treat nonresectable ductal cholangiocarcinoma: a Meta-analysis / 中华肝胆外科杂志

Objective To compare the therapeutic results of photodynamic therapy (PDT) combined with biliary stenting versus biliary stenting alone in the treatment of nonresectable bile duct cholangiocarcinoma.Methods The PubMed,CBM,CNKI,VIP and WanFang Data were searched from January 1990 to December 2017.Two researchers independently screened the literatures,extracted the data and performed the quality evaluation.The meta-analysis was carried out using the RevMan software 5.3.0.Results Eleven controlled clinical trials were included in the meta-analysis.There were only two randomized controlled trials.The remaining studies were non-randomized controlled trials.Finally,659 patients were enrolled in this study.293 patients were treated with photodynamic therapy and biliary stenting while 366 patients were treated with stenting alone.Analysis showed that photodynamic therapy combined with stenting significantly extended the overall survival when compared with stenting alone (P＜0.01).There was no significant differences in the incidences of cholangitis (P＞0.05),but PDT and stenting had a significantly higher total complication rate (P＜0.05).Conclusions This meta-analysis showed that photodynamic therapy combined with stenting significantly improved the survival rate of patients with nonresectable ductal cholangiocarcinoma when compared with stenting alone.Photodynamic therapy did not increase the incidence of cholangitis.

Primary hepatic leiomyosarcoma - A case report with review of literature.

Primary hepatic leiomyosarcoma are very rare tumours with less than 50 cases reported. Due to nonspecific presentations, diagnosis is often delayed until they reach a large size. The rarity of these tumours has precluded our understanding of them and therefore the standard of care has not been well defined. We report a 45-year-old lady who presented with loss of appetite, abdominal distension and bilateral lower limb swelling and hepatomegaly. CT abdomen revealed nodular hepatomegaly with a hypodense lesion on plain scans, heterogenous enhancing lesion on arterial phase and delayed washout on portal venous phase occupying segments VII and VIII and involving right hepatic vein and infiltrating into inferior vena cava (IVC). The pathology report confirmed the diagnosis of leiomyosarcoma. IHC was positive for SMA, vimentin and weakly positive for desmin stain. Due to extensive nature and involvement of IVC, patient was planned for upfront neo-adjuvant chemotherapy (NACT) (Ifosfamide, and doxorubicin with MESNA. The patient has completed 6 cycles NACT and had stable disease. The patient was then switched to oral Pazopanib and is on follow up.

Does the use of induction chemotherapy in oral cavity cancer compromise subsequent loco‑regional treatment delivery: Results from a matched pair analysis.

BACKGROUND: Neoadjuvant chemotherapy is being increasingly used in patients with unresectable oral cavity cancers to make them resectable. However, its impact on locoregional treatment delivery in such setting remains poorly studied. AIMS: To evaluate the impact of neoadjuvant chemotherapy on delivery of further locoregional treatment. SETTINGS AND DESIGN: Mono institutional retrospective audit of patients with oral cavity squamous cell cancers treated with neoadjuvant triplet chemotherapy in India. MATERIALS AND METHODS: Patients receiving neoadjuvant chemotherapy (n = 14) from May 2012 to April 2014 were matched 1:2 to patients undergoing upfront surgery (n = 28) based on age (>60 or 60 and less), gender (male or female) and subsite site (tongue and floor of mouth or buccoalveolar complex). Data regarding factors related to the delivery of locoregional treatment and toxicities were compiled. STATISTICAL ANALYSIS: Descriptive analysis in the form of median (range) for continuous variables and frequencies for categorical variables. RESULTS: Patients undergoing neoadjuvant chemotherapy required more extensive resections and had greater operative time (460 vs. 415 min, P < 0.001). A greater incidence of locoregional wound complications was seen as a consequence (57.1% vs. 14.3%, P, 0.01). However, toxicities during radiotherapy were not substantially different between the two groups and compliance to radiation was also similar. Total package time of 100 days or less, was maintained in 90% of patients in both groups. CONCLUSIONS: Delivery of neoadjuvant chemotherapy does not impair the ability to deliver locoregional treatment.

Role of neoadjuvant concurrent chemoradiation in locally advanced unresectable pancreatic cancer: A feasibility study at tertiary care centre.

BACKGROUND: Pancreatic cancer has an extremely poor prognosis and prolonged survival is achieved only by resection with macroscopic tumor clearance. There is a strong rationale for a neoadjuvant approach, since a relevant percentage of pancreatic cancer patients present with non‑metastatic but locally advanced disease. The objective of the present study was to assess the effect of neoadjuvant chemoradiation therapy (NACRT) on tumor response, down staging and resection, toxicity and any survival advantage. MATERIALS AND METHODS: A prospective pilot study was carried out from January 2009 to June 2011 in which 15 patients of locally advanced unresectable pancreatic cancer were included. All patients were treated with NACRT protocol with oral Capecitabine and 3D conformal radiotherapy (3DCRT) of 30 Gy in 10 fractions. The patients were restaged 3 to 4 weeks after the completion of NACRT and explored for resection. RESULTS: Out of 15 patients, fourteen were evaluable. Four patients underwent surgery, 5 had partial response but remained unresectable, 2 patients had stable disease and 3 had progressive disease. Most of the toxicities were slight and were in grade 1 to 2. None of the patients developed grade 3 or 4 gastrointestinal or hematological toxicity. The median survival was 15 months for resected patients and 8.6 months for unresected patients, respectively. The 2 year actuarial overall survival was 34.6%. CONCLUSION: All patients with locally unresectable pancreatic cancer should be offered chemoradiation therapy, in hopes of down staging the tumor for possible resection and achieving higher survival.

Referral pattern for neoadjuvant chemotherapy in the head and neck cancers in a tertiary care center.

BACKGROUND: Use of any treatment modality in cancer depends not only on the effectiveness of the modality, but also on other factors such as local expertise, tolerance of the modality, cost and prevalence of the disease. Oropharyngeal and laryngeal cancer are the major subsites in which majority of neoadjuvant chemotherapy (NACT) literature in the head and neck cancers is available. However, oral cancers form a major subsite in India. MATERIALS AND METHODS: This is an analysis of a prospectively maintained data on NACT in the head and neck cancers from 2008 to 2012. All these patients were referred for NACT for various indications from a multidisciplinary clinic. Descriptive analysis of indications for NACT in this data base is presented. RESULTS: A total of 862 patients received NACT within the stipulated time period. The sites where oral cavity 721 patients (83.6%), maxilla 41 patients (4.8%), larynx 33 patients (3.8%), laryngopharynx 8 patients (0.9%) and hypopharynx 59 patients (8.2%). Out of oral cancers, the major indication for NACT was to make the cancer resectable in all (100%) patients. The indication in carcinoma of maxilla was to make the disease resectable in 29 patients (70.7% of maxillary cancers) and in 12 patients (29.3% of maxillary cancers) it was given as an attempt to preserve the eyeball. The indication for NACT in laryngeal cancers was organ preservation in 14 patients (42.4% of larnyngeal cancer) and to achieve resectability in 19 patients (57.6% of larnyngeal cancer). The group with laryngopharynx is a cohort of eight patients in whom NACT was given to prevent tracheostomy, these patients had presented with early stridor (common terminology criteria for adverse events Version 4.02). The reason for NACT in hypopharyngeal cancers was for organ preservation in 24 patients (40.7% of hypopharyngeal cancer) and for achievement of resectability in 35 patients (59.3% of hypopharyngeal cancer). CONCLUSION: The major indication for NACT is to make disease resectable at our center while cases for organ preservation are few.

Tolerance and toxicity of neoadjuvant docetaxel, cisplatin and 5 fluorouracil regimen in technically unresectable oral cancer in resource limited rural based tertiary cancer center.

BACKGROUND: Recent studies indicate neoadjuvant chemotherapy (NACT) can result in R0 resection in a substantial proportion of patients with technically unresectable oral cavity cancers. However, data regarding the efficacy and safety of docetaxel, cisplatin and 5 fluorouracil (TPF) NACT in our setting is lacking. The present audit was proposed to evaluate the toxicities encountered during administration of this regimen. It was hypothesized that TPF NACT would be considered feasible for routine administration if an average relative dose intensity (ARDI) of ≥0.90 or more in at least 70% of the patients. MATERIALS AND METHODS: Technically unresectable oral cancers with Eastern Cooperative Oncology Group PS 0-2, with biopsy proven squamous cell carcinoma underwent two cycles of NACT with TPF regimen. Toxicity and response rates were noted following the CTCAE 4.03 and RECIST criteria. Descriptive analysis of completion rates (completing 2 cycles of planned chemotherapy with ARDI of 0.85 or more), reason for delay, toxicity, and response are presented. RESULTS: The NACT was completed by all patients. The number of subjects who completed all planned cycles of chemotherapy are with the ARDI of the delivered chemotherapy been equal to or >0.85 was 11 (91.67%). All toxicity inclusive Grade 3-5 toxicity was seen in 11 patients (91.67%). The response rate of chemotherapy was 83.33%. There were three complete response, seven partial response, and two stable disease seen post NACT in this study. CONCLUSION: Docetaxel, cisplatin and 5 fluorouracil regimen can be routinely administered at our center with the supportive care methods and precautionary methods used in our study.

Weekly chemotherapy as Induction chemotherapy in locally advanced head and neck cancer for patients ineligible for 3 weekly maximum tolerable dose chemotherapy.

OBJECTIVE: To study the safety and efficacy of weekly chemotherapy as part of induction chemotherapy, in locally advanced head and neck cancer for patients, who are unfit for upfront radical treatment. MATERIALS AND METHODS: It is a retrospective analysis of on‑use weekly chemotherapy as Induction chemotherapy in locally advanced head and neck cancer, who are technically unresectable are unfit for upfront radical treatment. Induction chemotherapy given was a 2 drug combination of paclitaxel (80 mg/m2) and carboplatin AUC 2. The decision to give weekly induction chemotherapy was given on the basis of presence of 2 more following features: Poor performance status (ECOG PS 2‑3), presence of uncontrolled co morbidities, BMI below 18.5 kg/m2 and age more than 60 years. The Statistical Package for the Social Sciences software (SPSS version 16.0) was used for analysis. The response rates, toxicity (accordance with CTCAE vs. 4.02), completion rate (Cp) of radical intent treatment post neoadjuvant chemotherapy (NACT), progression‑free survival (PFS) and overall survival (OS) are reported. RESULTS: Fifteen patients were considered for such therapy. Fourteen out of fifteen patients completed NACT. The median numbers of planned weekly cycles were 6 (3-8). Response (CR + PR) was seen in 10 patients. Overall grade 3-4 toxicity was seen in 6 patients. No toxicity related mortality was noted. The calculated completion rate (Cp) of radical intent treatment post NACT was 46.7%. The median PFS and OS were 10.36 months (95% CI 6.73-14.00 months) and 16.53 months (95% CI 4.22-28.84). CONCLUSION: Use of induction chemotherapy with weekly regimen is safe and effective selected cohort of patients with locally advanced disease who are unfit for upfront radical treatment.

Is there a role of induction chemotherapy followed by resection in T4b oral cavity cancers.

Objective: The objective of the following study is to investigate the efficacy and impact of induction chemotherapy in T4b oral cavity cancers. Materials and Methods: It's a retrospective analysis of prospectively collected data of T4b oral cavity cancer patients who were offered induction chemotherapy and then assessed for resectability at the end of 2 cycles of chemotherapy. Post-induction these patients either underwent surgical or non-surgical local intervention depending upon their response. These patients were then followed-up until either recurrence progression or death whichever was later. Statistical analysis was performed by SPSS version 16. Descriptive analysis was performed. Factors affecting achievement of resectability were sought by univariate and multivariate analysis. The impact of surgery on overall survival (OS) was studied using Kaplan Meier survival analysis with the use of log rank test. Results: A total of 110 patients received chemotherapy. Median age been 41.5 years (range 25-66 years). 21 (20%) of our patient received 3 drug regimen while the rest of our patients received 2 drug regimen. Partial response was achieved in 28 patients, stable disease in 49 patients and progression was noted in 23 patients. Resectability was achieved in 34 (30.9%) of 110 patients. The estimated median OS in patients who underwent surgery was 18.0 months (95% confidence interval [CI]: 13.6-22.46 months) and for those treated with non-surgical treatment was 6.5 months (95% CI: 5.6-7.4 months) (P = 0.0001). Conclusion: Use of induction chemotherapy is safe and can achieve resectability in 30.9% of our T4b patients. In those patients undergoing resection have much better OS then those who underwent non-surgical local treatment.

Induction might be beneficial in this setting by reducing tumor bulk and allowing definitive surgery. Aim: To analyze the impact of induction chemotherapy on locally advanced, technically unresectable oral cavity cancers. Materials and Methods: Retrospective analysis of patients with locally advanced oral cavity cancers, who were treated with neoadjuvant chemotherapy (NACT) during the period between June 2009 and December 2010. Data from a prospectively filled database were analyzed for information on patient characteristics, chemotherapy received, toxicity, response rates, local treatment offered, patterns of failure, and overall survival. The statistical analysis was performed with SPSS version 16. Results: 123 patients, with a median age of 42 years were analyzed. Buccal mucosa was the most common subsite (68.30%). Three drug regimen was utilized in 26 patients (21.10%) and the rest received two drug regimen. Resectability was achieved in 17 patients treated with 3 drug regimen (68.00%) and 36 patients receiving 2 drug regimen. Febrile neutropenia was seen in 3 patients (3.09%) receiving 2 drug regimen and in 9 patients (34.62%) receiving 3 drug regimen. The estimated median OS was not reached in patients who had clinical response and underwent surgery as opposed to 8 months in patients treated with non-surgical modality post NACT (P = 0.0001). Conclusion: Induction chemotherapy was effective in converting technically unresectable oral cavity cancers to operable disease in approximately 40% of patients and was associated with significantly improved overall survival in comparison to nonsurgical treatment.
