ABSTRACT

Abstract Case description: Case of lipemia retinalis secondary to hyperchylomicronemia in a 40-year-old man with a history of total body irradiation and immunosuppressive treatment that was attended in this hospital due to decreased visual acuity and abdominal pain. Clinical findings: Hyperchylomicronemia caused the development of acute pancreatitis and lipemia retinalis. The latter is an infrequent ocular manifestation that reflects excessive triglyceride blood levels in the organism (>2,000 mg/dL). Lipemia retinalis is characterized by the accumulation of chylomicrons in the retinal vessels, which gives them a white and creamy appearance in direct retinal ophthalmoscopy. The initial clinical suspicion of hyperchylomicronemia was based on the visualization of the supernatant in the analytical tube. Treatment and result: In the absence of definitive biochemical results, and owing to the need for special processing of the sample, lipid-lowering treatment and serum therapy were established after ophthalmological confirmation of lipemia retinalis, with subsequent full recovery of visual acuity. Clinical relevance: Given the initial difficulty to determine the accurate triglyceride levels in this kind of patient, early visualization of milky-colored retinal vessels on a salmon-colored eye fundus can help develop an early clinical suspicion of severe hyperchylomicronemia and contribute to limit the severity of complications.


Resumen Descripción del caso: Caso de lipemia retinalis secundaria a hiperquilomicronemia en varón de 40 años con antecedentes de irradiación corporal total y medicación inmunosupresora que acude al hospital por disminución de agudeza visual y dolor abdominal. Hallazgos clínicos: La hiperquilomicronemia contribuyó al desarrollo de pancreatitis aguda y lipemia retinalis. Esta última es una manifestación ocular infrecuente que refleja unos parámetros excesivos de triglicéridos en el organismo (>2,000 mg/dL). La Lipemia Retinalis consiste en la acumulación de quilomicrones en los vasos retinianos lo que les confiere un aspecto blanco y cremoso en la oftalmoscopia retiniana directa. La sospecha clínica inicial de hiperquilomicronemia se produjo por la visualización de sobrenadante en el tubo analítico. Tratamiento y resultado: Sin tener resultados definitivos bioquímicos, por necesidad de procesamiento especial de la muestra, se instauró tratamiento hipolipemiante y sueroterapia tras la confirmación oftalmológica de Lipemia Retinalis con recuperación total de la agudeza visual. Relevancia clínica: Dada la dificultad inicial para determinar las cifras reales de triglicéridos en este tipo de pacientes, la visualización precoz de vasos retinianos de color lechoso sobre lecho de color asalmonado en el fondo de ojo puede ser de ayuda para elaborar una sospecha clínica temprana de hiperquilomicronemia severa que contribuya a limitar la gravedad de las complicaciones.

ABSTRACT

Objective:To explore the effect of metastatic lymph node ratio (MLR) on the prognosis of adjuvant radiotherapy for stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection.Methods:According to the inclusion and exclusion criteria, a total of 590 patients diagnosed with stage-Ⅲ gastric cancer (excluding adenocarcinoma of esophagogastric junction) were included in this study from the SEER database between 2010 and 2016. No more than 15 lymph nodes were examined in all patients. Among them, 291 patients received surgery combined with adjuvant chemotherapy (surgery + chemotherapy group), and 299 patients received surgery combined with adjuvant radiochemotherapy (surgery + radiochemotherapy group). These two groups were treated with 1∶1 propensity score matching (PSM). We retrospectively analyzed the effect of MLR on prognosis of stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection, and evaluated the significance of postoperative adjuvant radiotherapy among patients with different MLR.Results:According to the analysis result of area under curve (ROC), 0.5 was defined as the best cut-off point of MLR. In the two groups of patients with stage-Ⅲ gastric cancer included in the study, the median survival time was 23 months in the surgery + radiochemotherapy group, and the 1 -, 3 -, and 5-year overall survival (OS) ratio were 77.1%, 33.2% and 22.8%, respectively. The median survival time was 21 months in the surgery + chemotherapy group, and the 1 -, 3 -, and 5-year OS ratio were 72.2%, 33.6% and 23.1%, respectively. There was no statistically significant difference between the two groups in OS. The result of subgroup analysis showed that there was no statistically significant difference in OS between the surgery + radiochemotherapy group and the surgery + chemotherapy group among patients with MLR≤0.5, while OS of the surgery + radiochemotherapy group was significantly better than the surgery + chemotherapy group among patients with MLR>0.5( χ2=8.542, P < 0.05). Multivariate Cox regression analysis showed that race, T stage, N stage, MLR and adjuvant radiotherapy were the important factors affecting OS of stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection( Wald=8.544, 7.547, 10.925, 18.047, 10.715, P < 0.05). After PSM, there was no statistically significant difference in OS between the two groups. The result of subgroup analysis showed that there was no statistically significant difference in OS between the surgery + radiochemotherapy group and the surgery + chemotherapy group among patients with MLR≤0.5, while OS of the surgery + radiochemotherapy group was significantly better than the surgery + chemotherapy group among patients with MLR>0.5( χ2=6.944, P < 0.05). Multivariate Cox regression analysis showed that race, T stage, N stage, MLR and adjuvant radiotherapy were the important factors affecting OS of stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection ( Wald=7.154, 8.023, 7.744, 17.016, 4.149, P < 0.05). The result of prognosis analysis of two groups before and after PSM were consistent. Conclusions:MLR is an important prognostic factor for stage-Ⅲ gastric cancer patients with no more than 15 lymph nodes dissection. The OS of patients with MLR ≤ 0.5 can′t benefit from postoperative adjuvant radiotherapy, while patients with MLR > 0.5 should be advised to receive postoperative adjuvant radiotherapy to improve the prognosis.

ABSTRACT

Introdução: O tratamento do câncer de mama inclui, além de terapias curativas, a reconstrução mamária. Entre as estratégias adjuvantes, a radioterapia fornece desfechos favoráveis em termos de redução da taxa de recorrência da doença. Esse estudo tem como objetivo comparar as diferenças histológicas entre mamas irradiadas e não irradiadas em um mesmo paciente. Métodos: Estudo prospectivo de coorte em pacientes submetidos à reconstrução mamária com prótese ou expansor sob retalho muscular de peitoral maior, comparando os padrões histológicos de pele, tecido celular subcutâneo, músculo peitoral maior e cápsula do implante, de mamas irradiadas e não irradiadas em amostras pareadas de um mesmo paciente. Todos os pacientes deveriam receber irradiação em apenas uma das mamas. A análise anatomopatológica foi comparada aos achados clínicos e aos aspectos macroscópicos do transoperatório. Resultados: O trabalho contou com um total de 7 pacientes, sendo a idade média de 52,15 anos. Os principais achados histológicos em pele e tecido celular subcutâneo da mama irradiada foram: hiperplasia epidérmica, achatamento da camada papilar, atrofia dos apêndices dérmicos, congestão vascular no tecido gorduroso, alta densidade das fibras de colágeno dérmico, hialinização das paredes vasculares, redução das fibras elásticas na derme profunda e alinhamento unidirecional das fibras de colágeno. Os principais achados histológicos de cápsula e músculo peitoral maior na mama irradiada foram: menor densidade de fibras elásticas, fibrose perivascular, metaplasia sinovial, sequestro de músculo esquelético na interface com a cápsula, hialinização capsular e fibroesclerose capsular. Conclusão: Encontramos alterações histológicas comuns nas mamas irradiadas em boa parte das pacientes, achados esses que são compatíveis com as alterações clínicas e macroscópicas observadas. Esse estudo apresenta-se como um piloto para o desenvolvimento de novos estudos que pesquisem os mecanismos fisiopatológicos relacionados às alterações histológicas descritas.


Introduction: The treatment of breast cancer includes not only curative therapies but also breast reconstruction. Radiotherapy, an adjuvant strategy, provides favorable outcomes by reducing the rate of recurrence of the disease. This study aimed to compare histological differences between irradiated and non-irradiated breasts in the same patient. Methods: This is a prospective cohort study of patients undergoing breast reconstruction with prosthesis or expander under pectoralis major muscle flap that compared histological skin patterns, subcutaneous cell tissue, pectoralis major muscle, and implant capsule of irradiated and non-irradiated breasts in paired samples of the same patient. All patients included in this study were irradiated in only one breast. The results of the anatomopathological analysis were compared to clinical findings and intraoperative macroscopic aspects. Results: The study included a total of 7 patients with a mean age of 52.15 years. The main histological findings in the skin and subcutaneous cellular tissue of the irradiated breast were as follows: epidermal hyperplasia, flattening of the papillary layer, atrophy of the skin appendages, vascular congestion in fatty tissue, high density of skin collagen fibers, hyalinization, and reduction of elastic fibers in the deep dermis and unidirectional alignment of collagen fibers. The main histological findings for the capsule and pectoralis major muscle in the irradiated breast were as follows: lower density of elastic fibrosis, perivascular fibrosis, synovial metaplasia, skeletal muscle sequestration at the interface with the capsule, capsular hyalinization, and capsular fribrosclerosis. Conclusion: We found common histological changes in irradiated breasts in most patients. These findings are compatible with the clinical and macroscopic changes observed. This study presents itself as a pilot for the development of further studies investigating the physiopathological mechanisms of the described histological changes.

ABSTRACT

PURPOSE: The purpose of this study was to investigate the non-inferiority of omitting radiotherapy (RT) after breast-conserving surgery (BCS) for hormone receptor (HR)‒positive T1N0 breast cancer in elderly women. MATERIALS AND METHODS: From 2004 to 2014, HR-positive T1N0 breast cancer patients aged 50 years or older and receiving BCS were retrieved from the Surveillance, Epidemiology, and End RESULTS: 18 database. After propensity score matching between the no-RT and RT groups, univariate and multivariate analyses were performed. Identified prognostic factors were used to stratify the risk groups. In each risk group, 10-year cancer-specific survival (CSS) rates were compared between the no-RT and RT groups. RESULTS: After propensity score matching, the numbers of patients in the no-RT and RT groups were both 18,586. For patients who satisfied both a tumor size of 1-10 mm and a tumor grade of 1-2, omitting RT did not decrease the CSS rate at any age group, ranging from ≥ 50 to ≥ 85 years; for patients aged ≥ 50 years, the 10-year CSS rates in the no-RT and RT groups were 97.2% and 96.8%, respectively (adjusted hazard ratio, 0.862; p=0.312). However, for patients with a tumor size of 11-20 mm or tumor grade of 3-4, RT significantly increased the CSS rate irrespective of age. CONCLUSION: RT after BCS for HR-positive T1N0 breast cancer in elderly women might be omitted without causing a decrease in the CSS rate, but only in patients who satisfy both a small tumor size (≤ 10 mm) and low tumor grade (1-2).

ABSTRACT

Background@#Organ preservation has long been a consideration in the treatment of supraglottic and hypopharyngeal carcinoma to improve the quality of life (QOL). Definitive radiotherapy (DRT) with or without systematic treatment, such as chemotherapy, is always the first choice to achieve improved QOL. This retrospective study focused on the survival differences between DRT and surgery followed by adjuvant radiotherapy (S + RT) in supraglottic and hypopharyngeal carcinoma.@*Methods@#This study included adult patients with supraglottic or hypopharyngeal carcinoma undergoing single-modality treatment with either DRT or S + RT between January 2012 and August 2016. A total of 59 patients were identified, of whom 31 were treated with DRT, and 28 were treated with S + RT. In the 31 cases of DRT, 23 cases were treated with concurrent chemoradiotherapy (CRT), one case was treated with DRT plus cetuximab, and seven cases were treated with DRT alone. Of the other 28 cases of S + RT, 15 cases were treated with adjuvant concurrent CRT. Survival analysis was used to compare the overall survival (OS), local recurrence-free survival (LRFS) and distant metastasis-free survival (DMFS) between DRT and S + RT groups.@*Results@#The median follow-up was 20 months (range, 4-67 months). The patients of the two groups were similar with respect to mean age, original sites, and tumor stages. The 1-, 2-, and 5-year OS rates were 80.6%, 53.4%, and 24.7% for the DRT group and 85.7%, 67.1%, and 24.7% for the S + RT group, respectively. There was no significant difference between the two groups (χ2 = 3.183, P = 0.074). The 1-, 2-, and 5-year LRFS and DMFS were 90.4%, 61.7%, and 18.0% and 87.4%, 49.2%, and 9.9%, respectively, and no statistical difference was observed between the two groups (LRFS: χ2 = 0.028, P = 0.868; DMFS: χ2 = 3.347, P = 0.067). No significant difference was found between the two groups in acute radiotoxicity.@*Conclusions@#Without loss of laryngeal function, the survival of DRT is comparable to that of S + RT in supraglottic and hypopharyngeal carcinoma.

ABSTRACT

Objective@#To investigate the dose characteristics and outcomes of a single isocenter bilateral tangential fields (IBTF) combined with intensity-modulated radiotherapy (IMRT) in bilateral breast radiotherapy (BBR).@*Methods@#Fourteen female patients with synchronous bilateral breast cancer (SBBC) after breast-conserving surgery (BCS) were enrolled in this study. All patients received BBR using IBTF combined with IMRT at a conventional (50 Gy/25f) or hypofractionated (43.5 Gy/15f) dose. For patients with invasive cancer, the additional tumor bed boost was given with sequential electron radiation or simultaneously photon IMRT. The coverage, uniformity and short-term clinical efficacy were evaluated.@*Results@#The number of the irradiation field was 8-11, including 4-7 intensity-modulated fields. The bilateral breast PTV dose coverage reached 95% in all plans. For the tumor bed, the mean dose coverage was (95.54±1.33)%(left) and (94.19±1.03)%(right) using photon, and (90.25±8.79)%(left) and (85.28±8.35)%(right) using electron. The average V20 of bilateral lungs was (16.69±3.90)%. The cardiac Dmean was 5.48 Gy. Three patients presented with grade Ⅱ acute skin toxicities. No ≥ grade Ⅱ pneumonitis was observed. No recurrence occurred with the median follow-up time of 30.1 months. Eleven patients showed excellent cosmetic results.@*Conclusion@#BBR using IBTF combined with IMRT is efficacious and safe for patients with SBBC after BCS.

ABSTRACT

Objective To compare the efficacy of neoadjuvant radiotherapy and adjuvant radiotherapy in the treatment of patients who underwent radical esophagectomy for T3 N0 stage. Methods Totally 555 cases of T3 N0 , who underwent t neoadjuvant radiotherapy or adjuvant radiotherapy from 2004 to 2014, were selected from the SEER cancer registry in this study. 486 cases received neoadjuvant radiotherapy ( neoadjuvant radiotherapy group ) and 69 cases received adjuvant radiotherapy ( adjuvant radiotherapy group). Kaplan-Meier (KM) survival and multivariate Cox regression analyses were used to analyze the overall survival ( OS) and cancer specify survival ( CSS) of the two groups. A propensity score model was utilized to balance the baseline covariates. Results The CSS in the neoadjuvant radiotherapy group was significantly better than that in the adjuvant radiotherapy group (χ2 = 6. 030, P<0. 05 ) . Multivariate COX regression analysis showed that age, gender, and radiotherapy sequence with surgery were important factors influencing the prognosis of esophageal cancer with T3N0 stage ( Wald=10. 099, 10. 562, 4. 331, P<0. 05) . Compared with the neoadjuvant radiotherapy group, the adjuvant radiotherapy group had a worse CSS ( hazard ratio:1. 649, 95%CI 1. 173-2. 316, P=0. 004) and OS ( hazard ratio:1. 402, 95%CI 1. 020-1. 928, P=0. 037) . According to K-M survival analysis, the adjuvant radiotherapy group showed the worse CSS ( hazard ratio: 1. 813, 95%CI 1. 072-3. 069, P=0. 027) and OS ( hazard ratio: 1. 424, 95% CI 0. 896-2. 262, P=0. 134) than the neoadjuvant radiotherapy in esophageal cancer with T3N0 stage, which was similar to the matched cohort. Conclusions Compared with postoperative adjuvant radiotherapy, neoadjuvant radiotherapy significantly improves the CSS and OS of T3 N0 patients with esophageal cancer.

ABSTRACT

@#Osteosarcoma is the most common osteogenic malignancy of the head and neck, and its incidence in the upper mandible is predominant. Osteosarcoma of the head and neck has various causes and rich pathological subtypes. Diagnosis of osteosarcoma requires the synthesis of symptoms and imaging data and pathological characteristics (including cell characteristics, immunohistochemical characteristics and molecular markers). Surgery is the core treatment for osteosarcoma of the head and neck. Compartment resection based on the Enneking staging system has high practicability in the surgical treatment of osteosarcoma of the head and neck. Osteosarcoma can be treated by combined craniomandibular surgery to achieve complete resection of the tumor. The combination of adjuvant radiotherapy, adjuvant chemotherapy and surgery can further reduce the risk of local recurrence and distant tumor metastasis. The emergence of targeted therapy and immunotherapy provides more options for the treatment of head and neck osteosarcoma. This article reviews the diagnosis and treatment of osteosarcoma of the head and neck.

ABSTRACT

Eccrine porocarcinoma is a rare malignant tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It develops either spontaneously or from a long standing benign eccrine poroma. This entity usually affects older people and is commonly located on the lower extremities, the trunk, and the head. We report a case of eccrine porocarcinoma on the left cheek in an 85-year-old male. In our case, the tumor was treated with wide excision and postoperative adjuvant radiation therapy. The patient recovered well without local recurrence and distant metastasis during the 14-month follow-up period. Wide excision and postoperative adjuvant radiation therapy can be considered as a safe and effective treatment option in treating patients with eccrine porocarcinoma.

ABSTRACT

PURPOSE: To identify prognostic factors influencing progression-free survival (PFS) of aggressive fibromatosis (AF) after postoperative radiotherapy (PORT) and assess correlations between immunohistochemistry (IHC) features of β-catenin/smooth muscle actin (SMA) and PFS. MATERIALS AND METHODS: Records of 37 patients with AF treated by PORT from 1984 to 2015 were retrospectively reviewed. Fifteen patients underwent wide excision for AF and 22 patients received debulking operation. The median total dose of PORT was 59.4 Gy. IHC staining results of β-catenin and SMA were available for 11 and 12 patients, respectively. RESULTS: The median follow-up duration was 105.9 months. Five-year PFS rate was 70.9%. Tumor size or margin status was not related to PFS in univariate analysis (p = 0.197 and p = 0.716, respectively). Multivariate analysis showed that increased interval from surgery to PORT (>5.7 weeks) was a marginal risk factor for PFS (p = 0.054). Administration of PORT at the initial diagnosis resulted in significantly improved PFS compared to deferring PORT after recurrence (p = 0.045). Patient with both risk factors of deferring PORT after recurrence and interval from surgery to PORT >5.7 weeks had significantly lower 5-year PFS than patients without risk factor (34.1% vs. 100.0%; p = 0.012). Nuclear β-catenin intensity tended to inversely correlate with 5-year PFS, although it did not reach statistical significance (62.5% at low vs. 100.0% at high; p = 0.260). SMA intensity was not related to PFS (p = 0.700). CONCLUSION: PORT should be performed immediately after surgery irrespective of margin status or tumor size especially in recurrent case. Nuclear β-catenin staining intensity of IHC might correlate with local recurrence.

ABSTRACT

PURPOSE: An enhanced recovery after surgery (ERAS) protocol incorporates up-to-date perioperative care principles; the primary aim in using an ERAS protocol is to reduce issues that delay the recovery and cause the complications. The aim of this study was to compare outcomes associated with head and neck cancer surgery with free-flap reconstruction before and after implementation of an ERAS protocol. METHODS: Outcomes were analyzed by dividing patients into 2 groups: 29 patients in the non-ERAS group and 60 patients in the ERAS group. The ERAS group performed a prospective observational cohort study of patients who underwent a head and neck cancer surgery with free-flap reconstruction in Ajou University Hospital from August 2015 to December 2017. The non-ERAS group retrospectively reviewed the medical records of patients who had undergone the same surgery from August 2012 to July 2015. RESULTS: Demographics, comorbidities, hospital length of stay (LOS), postoperative complications, starting time of rehabilitation, and postoperative periods before radiotherapy for the non-ERAS and ERAS groups were compared. Hospital LOS was significantly lower for patients whose care followed the ERAS protocol than for patients in the non-ERAS group (30.87 ± 20.72 days vs. 59.66 ± 40.43 days, P < 0.0001). CONCLUSION: In this study, hospital LOS was reduced through fast recovery after the implementation of the ERAS protocol. Therefore, the ERAS protocol appeared feasible and safe in head and neck cancer surgery with free-flap reconstruction.

ABSTRACT

PURPOSE: This study aimed to identify predictors for distant metastatic behavior and build a related prognostic nomogram in breast cancer. MATERIALS AND METHODS: A total of 1,181 patients with non-metastatic breast cancer between 2003 and 2011 were analyzed. To predict the probability of distant metastasis, a nomogram was constructed based on prognostic factors identified using a Cox proportional hazards model. RESULTS: The 7-year overall survival and 5-year post-progression survival of locoregional versus distant recurrence groups were 67.6% versus 39.1% (p=0.027) and 54.2% versus 33.5% (p=0.043), respectively. Patients who developed distant metastasis showed early and late mortality risk peaks within 3 and after 5 years of follow-up, respectively, but a broad and low risk increment was observed in other patients with locoregional relapse. In multivariate analysis of distant metastasis-free interval, age (≥ 45 years vs. < 45 years), molecular subtypes (luminal A vs. luminal B, human epidermal growth receptor 2, and triple negative), T category (T1 vs. T2-3 and T4), and N category (N0 vs. N1 and N2-3) were independently associated (p < 0.05 for all). Regarding the significant factors, a well-validated nomogram was established (concordance index, 0.812). The risk score level of patients with initial brain failure was higher than those of non-brain sites (p=0.029). CONCLUSION: The nomogram could be useful for predicting the individual probability of distant recurrence in breast cancer. In high-risk patients based on the risk scores, more aggressive systemic therapy and closer surveillance for metastatic failure should be considered.

ABSTRACT

BACKGROUND: Penile cancer is a rare malignancy associated with high rates of mortality and morbidity. Currently, the efficacy of adjuvant treatment (AT), including radiotherapy and chemotherapy, for penile cancer remains unclear. Therefore, we investigated the prognostic factors for treatment outcomes and the efficacy of AT in consecutive patients who underwent penectomy for penile cancer at multiple Korean institutions between 1999 and 2013. METHODS: AT was defined as the administration of chemotherapy, radiotherapy, or both within 12 months after initial treatment. All patients were divided into two groups according to the AT status. RESULTS: Forty-three patients (median age 67.0 years) with a median follow-up after penectomy of 26.4 (interquartile range: 12.0–62.8) months were enrolled. Patients with AT had a significantly higher pathologic stage. However, no differences in age, histologic grade, or type of surgery were identified according to the presence of AT. The 3- and 5-year cancer-specific survival (CSS) rates were 79.0% and 33.0%, respectively. In a multivariate analysis, American Joint Committee on Cancer (AJCC) stage ≥ III disease was an independent predictor of CSS and recurrence-free survival (RFS). However, AT was not associated with CSS and RFS. The type of primary surgical treatment and inguinal lymph node dissection at diagnosis were also not significantly associated with overall survival, CSS, or RFS. CONCLUSION: AJCC stage ≥ III disease, which mainly reflects lymph node positivity, is a significant prognosticator in patients with penile cancer. By contrast, AT does not seem to affect CSS and RFS.

ABSTRACT

Lateral neck metastasis is an independent risk factor of the loco-regional recurrence in papillary thyroid carcinoma (PTC). Ultrasonography (US) and computed tomography are frequently performed to diagnose the lymph node (LN) metastasis. However, some metastatic LNs can remain after initial treatment and can present as regional recurrences. A 19-year-old woman was diagnosed as having 1.99 cm PTC. No abnormal LNs was detected on preoperative CT and US. She underwent operation and radioactive iodine (RAI) therapy: seven months after RAI therapy, thyroglobulin level was elevated. However, no metastatic LNs were detected on neck CT, US and positron emission tomography-CT. Neck exploration was performed and metastatic PTC was diagnosed in bilateral level III and IV. A radiologist retrospectively reviewed the neck CTs taken before the first surgery and the second surgery. There was no significant difference in the LN appearances of two CTs. On both CT scans, all LNs were very small, homogenously enhanced, without calcification or cystic changes.

ABSTRACT

@#Objective    To evaluate the strategy of chemoradiotherapy following endoscopic R0 resection for esophageal cancer in M3-T1b stage. Methods    There were 45 esophageal cancer patients with M3-T1b stage with endoscopic R0 resection followed by additional chemoradiotherapy from ECETC (Esophageal Cancer Endoscopic Therapy Consortium) as a trial group with 34 males and 11 females at age of 61.37±7.14 years. There were 90 patients with esophagectomy from Fudan University Shanghai Cancer Center as a control group with 63 males and 27 females at age of 61.04±8.17 years. Propensity score match (1:2) was used to balance the factors: gender, age, position, depth of invasion and lymphovascular invasion (LVI), which may influence the outcomes. Overall survival (OS) rate, relapse free survival (RFS) rate, and local recurrence rate were compared between the two groups. Result    There was no statistical difference (HR=2.66 with 95%CI 0.87 to 8.11, P=0.179) in terms of OS rate between the two groups. One, two and three years overall survival rate of patients in the control group was 93%, 86%, and 84%, respectively. Nobody died in the trial group within 3 years after surgery. The RFS rate between the two groups didn’t significantly differ (HR=1.48, 95% CI 0.66 to 3.33, P=0.389). One, two and three years RFS rate of patients in the contorl group was 87%, 78%, and 76%, respectively, while 97%, 93%, and 73% in the trial group, respectively. The local recurrence rates between the two groups didn’t significantly differ either ( HR=0.53,95%CI 0.13 to 2.18, P=0.314). One, two and three years local recurrence rate of patients in the control group was 5%, 6% and 6%, respectively, while 0%, 0% and 21% in the trial group, respectively. Conclusion    Similar outcomes are found regarding OS, RFS and local recurrence rates between the two groups. The strategy of endoscopic R0 resection followed by additional chemoradiotherapy has prospect for the treatment of esophageal cancer in M3-T1b stage. And this kind of therapy may be provided for those with risk factors or can not tolerate surgery.

ABSTRACT

PURPOSE: Soft tissue sarcoma (STS) is a rare and heterogeneous cancer with over 50 known subtypes. It is difficult to understand the role of adjuvant treatment in STS. We aimed to determine the benefits of adjuvant treatment for a rare STS subset: non-extremity STS with moderate chemosensitivity. MATERIALS AND METHODS: We reviewed medical records from Pusan National University Hospital and Kosin University Gospel Hospital, which had detailed pathological reports on patients diagnosed between 2006 and 2016. The most important inclusion criterion was resection with curative intent. We grouped STS by chemosensitivity based on reported data and analyzed non-extremity STS with moderate chemosensitivity. RESULTS: We investigated 142 patients with 20 pathological subtypes of STS. Eighty-six patients had extremity STS and 56 had non-extremity STS. Thirty-eight of 56 patients were categorized as having moderate chemosensitivity. Seventeen of 38 patients (44.7%) received adjuvant radiotherapy and 14 (36.8%) received adjuvant chemotherapy. A log-rank test showed longer disease-free survival (DFS) in the adjuvant radiotherapy group than in the group treated without adjuvant radiotherapy (not reached vs. 1.468 years, p = 0.037). Multivariate Cox proportional hazard analysis, with covariates including age, stage, resection margin, adjuvant chemotherapy, and adjuvant radiotherapy, revealed that adjuvant radiotherapy was associated with longer DFS (odds ratio = 0.369, p = 0.045). Overall survival was not correlated with adjuvant radiotherapy. CONCLUSION: Adjuvant radiotherapy may be associated with longer DFS in patients with non-extremity STS with moderate chemosensitivity.

ABSTRACT

Chest?regional recurrence and metastasis are the main modes of treatment failure after surgery for patients with esophageal cancer. As one of the primary approaches for local therapy, radiotherapy has a satisfactory efficacy in the reduction of postoperative chest?regional recurrence in patients with esophageal cancer. Right now, the value of postoperative adjuvant therapy for patients with positive lymph nodes has been widely recognized by clinicians. Postoperative adjuvant chemoradiotherapy has become a standard treatment mode. However, there is no consensus on whether adjuvant radiotherapy should be performed in patients with negative lymph nodes. To determine whether patients with stage pN0 esophageal cancer should receive postoperative adjuvant therapy, this paper reviews the current research advances in possible evidence for the necessity of postoperative adjuvant radiotherapy for patients with stage pN0 esophageal cancer, current related reports, and the effects of different surgical methods on treatment outcomes of postoperative adjuvant therapy.

ABSTRACT

Recently, it has been suggested that the guideline for adjuvant radiotherapy (ART) following radical prostatectomy (RP) sponsored by the American Urological Association and American Society for Radiation Oncology (AUA/ASTRO) may result in a significant overtreatment. Thus, the objective of the present study was to refine the AUA/ASTRO guideline for ART in patients at risk for biochemical recurrence (BCR) after RP. To this end, we reviewed our prospectively maintained database and selected 193 patients who met the AUA/ASTRO ART criteria. With a median follow-up of 24.0 months, BCR rate was 17.6% (34/193). When stratified by the Gleason score, BCR rate in men with Gleason score 6 was 6.8%. There was no significant association between BCR-free survival and surgical margin (P = 0.690) and pathologic stage (P = 0.353) in patients with the Gleason score 6. However, in patients with positive surgical margins (PSMs)/pathologic stage ≥T3, there was a significant difference in BCR-free survival according to Gleason score (≤14;7 vs 8-10, P = 0.047). Multivariate Cox regression analysis demonstrated that pathologic stage ≥T3 (HR = 2.106; P= 0.018), PSMs (HR = 2.411; P= 0.003), and pathologic Gleason score 8-10 (HR = 4.715; P< 0.001) were independent predictors of BCR after RP. Therefore, in addition to pathologic stage ≥T3 and PSMs, Gleason score 8-10 predicts BCR after RP. In patients with Gleason score 6, observation rather than ART may be more appropriate regardless of stage and surgical margin status.
