RESUMO

A man in his 70s was concurrently suspected of having a submucosal tumor(SMT)of the stomach and a liver tumor during a medical examination. Abdominal contrast-enhanced CT scan revealed S8 hepatocellular carcinoma(HCC)and an SMT of the stomach, which was strongly enhanced from the early to the later phase. Upper gastrointestinal endoscopy revealed a 20 mm SMT in the antrum of the stomach. Endoscopic ultrasonography showed a hyperechoic tumor in the fourth layer of the gastric wall. T2-weighted MRI showed a 25 mm SMT in the antrum of the stomach with a faint high signal intensity compared with that of the gastric wall. The patient was diagnosed with HCC and gastric glomus tumor, and a liver segmentectomy and a local gastrectomy were performed. Immunohistochemistry of the SMT revealed the expression of α-SMA but no expression of desmin, c-kit, CD34, or S-100. Therefore, a diagnosis of a Glomus tumor of the stomach was made. Gastric Glomus tumors are very rare; therefore, we have reviewed some citations and would like to discuss our case.

RESUMO

A case was 73-year-old man, who had history of laparoscopic high anterior resection surgery for rectal cancer, followed by adjuvant chemotherapy 2 years ago. Preoperative diagnosis was anterior mediastinal tumor, with multiple intrapulmonary nodules noted, though no increasing tendency. During adjuvant chemotherapy for colorectal cancer, the anterior mediastinal tumor showed some shrinkage, while that and 3 intrapulmonary nodules slowly increased in size after completion, thus rectal cancer pulmonary and mediastinal metastasis were suspected. Complete resection of the intrapulmonary nodules and anterior mediastinal tumor was considered feasible. Thoracoscopic observation revealed multiple small pleural seeding lesions and all speculated to be intrapulmonary metastases before surgery were also pleural lesions. Intraoperative rapid diagnostic findings of a biopsy section revealed possible colorectal cancer metastasis, though histological type was not revealed. Final histopathological diagnosis was pleural dissemination of thymic carcinoma. Lenvatinib was introduced 2 months later for thymic carcinoma with pleural dissemination. Two years after surgery, the anterior mediastinum primary tumor had slightly decreased and the pleural nodules also showed a shrinking tendency. In such cases of small tumor with increasing tendency and irregular margins, thymic carcinoma should be considered when planning treatment.

RESUMO

Hypertrophic pulmonary osteoarthropathy(HPO)is a tumor-associated syndrome that features the triad of clubbed fingers, periosteal bone growth in long bones, and arthritis, and is often associated with an adenocarcinoma or squamous cell carcinoma. This report presents details of a case of HPO associated with pleomorphic carcinoma, which was relieved by treatment. A 47-year-old woman was presented with a complaint of generalized arthralgia. A physical examination showed swollen joints in the body and clubbed fingers. Chest CT revealed a mass shadow in the left upper lobe and ultrasound- guided biopsy findings led to a diagnosis of non-small cell lung cancer. Furthermore, bone scintigraphy indicated symmetrical accumulation in bones and joints throughout the body. A right upper lobectomy was performed along with combined chest wall resection and mediastinal lymph node dissection with an open chest, and the presence of lung cancer complicated with HPO was indicated. Pathological examination results revealed a diagnosis of pleomorphic carcinoma(pT4N0M0, Stage ⅢA). Systemic arthralgia was resolved on the first postoperative day. One year after surgery, a solitary brain metastasis developed and was removed, with no recurrence at the time of writing. Joint symptoms related to HPO can be expected to improve with treatment of pulmonary lesions, thus aggressive procedures for diagnosis and treatment are desirable.

RESUMO

We report 2 cases of recurrent colon cancer with BRAF mutation. Case 1, a 75-year-old man, had rapid progress of multiple liver metastasis 5 months after curative resection, and died on 37 days after recurrence without induction of systemic therapy. Case 2, a 67-year-old man with diagnosis of peritoneal dissemination at 8 months after curative resection, received encorafenb and cetuximab (doublet-therapy) with certain effect, nevertheless advanced triplet-therapy with binimetinib was forced to pause due to severe skin disorders and he died on 123 days after recurrence. We considered that closed follow- up should be required after curatively resected colorectal cancers with BRAF mutation for early detection of recurrence, and prompt induction and evaluation of systemic treatment also should be required after unresectable recurrence including careful management with the attention to the features of doublet and triplet-therapy.

RESUMO

INTRODUCTION: In our hospital, we measure the body composition of patients undergoing gastrointestinal surgery. For patients who have a skeletal muscle mass(SMM)of less than 90% of the ideal, we provide them with guidance on having oral nutritional supplements(ONS)and self-exercise therapy. Therefore, we perform operations after taking measures on preserving/improving patient's preoperative conditions. This study was aimed to evaluate the effects on body weight, SMM, and fat mass(FM)in the patients scheduled for gastrectomy. PATIENTS AND METHODS: From January 2017 to December 2020, we retrospectively analyzed 64 gastric cancer patients whose body composition changes were measured at the time of initial diagnosis and immediately before surgery. The body composition was measured by a nutritionist using the BIA method, while the self-exercise therapy was instructed by a rehabilitation therapist. RESULTS: A total of 64 patients were divided into 2 groups: ONS group(36 patients)and Non-ONS group(28 patients). The median preoperative ONS administered to the ONS group was 15 packs. Body weight change showed a significant difference between the 2 groups(+0.73% and -0.91%[p<0.01]in the ONS group and Non-ONS group respectively). SMM change showed no significant difference between the 2 groups(+1.18% and +0.64%[p=0.19]in the ONS group and Non-ONS group respectively). Likewise, FM change showed no significant difference between the 2 groups(-1.08% and -3.50%[p=0.39]in the ONS group and Non-ONS group respectively). CONCLUSION: This study suggested that SMM and FM could be preserved, and body weight could be increased by the support of preoperative ONS administration even in patients with gastric cancer close to having sarcopenia.

RESUMO

BACKGROUND: Surgical resection is the first-choice treatment for operable liver metastases from pancreatic neuroendocrine tumors (pNETs). However, radiofrequency ablation, transcatheter arterial chemoembolization, and interventional radiology are expected to control local disease activity and improve survival rates in patients not eligible for surgery. PRESENTATION OF CASE: A 54-year-old woman underwent pancreaticoduodenectomy for treatment of an 80-mm-diameter pancreatic head tumor. Histologically, the pancreatic tumor was diagnosed as a nonfunctional pNET (G2). At 38 months postoperatively, abdominal computed tomography showed two 15-mm-diameter liver tumors in segment 3 and segment 5/6, respectively. The patient requested nonsurgical treatment. Therefore, radiofrequency ablation combined with transcatheter arterial embolization was performed for the liver metastases. No complications occurred after the therapy. She was alive without recurrence at the time of this writing (33 months after the liver metastasis therapy, 74 months after the operation). DISCUSSION: Although interventional radiology and radiofrequency ablation should be very carefully performed after pancreaticoduodenectomy or biliary reconstruction, our patient showed a good response to treatment without serious complications. CONCLUSION: This report details our experience in treating liver metastasis from a pNET after pancreaticoduodenectomy. The metastasis was successfully treated by radiofrequency ablation combined with transcatheter arterial embolization.

RESUMO

INTRODUCTION: Squamous cell carcinoma (SCC) of the gallbladder is rare, accounting for merely 1-3% of all gallbladder cancers. PRESENTATION OF CASE: A 59-year-old Japanese man was referred to our hospital with a chief complaint of right lower abdominal pain. He was diagnosed with gallbladder cancer after comprehensive testing. Computed tomography (CT) imaging revealed an enlarged gallbladder, and a lumen full of tumors (maximum tumor size was 90 mm in diameter.). The patient was, therefore, admitted to our department for the operation. After admission, the patient developed a fever and pain in his lower right abdomen. Palpation revealed masses in the abdomen and right hypochondrium. Blood tests revealed elevated levels of inflammatory markers. Therefore, a conservative treatment approach was performed prior to surgery. After then, the patient's abdominal symptoms did not seem to worsen, and his vital signs were stable, leading us to continue the conservative treatment approach. The operation was conducted on a semi-urgent basis. Surgical findings: The patient was diagnosed with gallbladder cancer with traverse colon infiltration. We performed hepatic resection (S4a + S5), biliary reconstruction, lower (pyloric) gastrectomy, right hemicolectomy, and ileostomy. Histopathological findings revealed that the patient was diagnosed with advanced gallbladder SCC. DISCUSSION: Primary SCC of the gallbladder is associated with poor prognosis. Continuing to collect and document such cases will help to resolve this matter. CONCLUSION: This report details our experience in treating a case of "pure" gallbladder SCC, a rare subtype of gallbladder cancer. Despite the complicating general peritonitis, we were still able to safely perform a radical resection to remove it.

RESUMO

A 57-year-old man underwent curative resection for Stage Ⅰ sigmoid colon cancer; 6 years later, lung metastasis was detected and subsequently resected. Eight years after the first curative resection, retroperitoneal metastasis was detected and subsequently resected. Nine years after the first curative resection, a growing tumor was detected at the bottom of the right lower lobe of the lung. Partial lung resection was performed; pathological examination revealed a secondary tumor formed as a result of colon cancer metastasis. When we searched previous cases of late recurrence in colorectal cancer, the primary colorectal cancer was classified as StageⅠ or Ⅱ in more than half of the cases. Therefore, even after curative resection of Stage Ⅰ colon cancer, late recurrences may occur.

RESUMO

A 71-year-old woman with advanced ascending colon cancer was admitted to our hospital. Abdominal computed tomography( CT)revealed locally advanced sigmoid colon cancer with suspected invasion of the liver and duodenum. The clinical stage of the disease was cT4bN3M1a, cStage Ⅳa, with wild-type RAS and UGT1A1 expression. An ileostomy was performed because of bowel obstruction. The patient received 6 courses of FOLFOXIRI plus bevacizumab(Bev). The only adverse event was Grade 3 neutropenia. Laparoscopic right hemicolectomy with lymph node dissection was performed. The pathological diagnosis was the absence of viable, Grade 3 carcinoma cells. This result suggested that preoperative FOLFOXIRI plus Bev chemotherapy is useful for the treatment of locally advanced colon cancer.

RESUMO

BACKGROUND/AIM: If both distant metastases and the primary tumour of colorectal cancer (CRC) are resectable, resection of the distant metastases is considered. The aim of this retrospective study was to determine the efficacy of curative resection of both primary and metastatic lesions in organs other than liver or lung in CRC patients. PATIENTS AND METHODS: The medical records of 23 CRC patients who received R0 resection for primary and metastatic regions between 2009 and 2018 were retrospectively analyzed. RESULTS: The 3-year overall survival (OS) in all 23 cases was 80.0%. There was no clinicopathological factor associated with OS on univariate analysis. CONCLUSION: Curative surgical resection appears to be useful for distant CRC metastases to organs other than liver or lung.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the feasibility of a protocol for enhanced recovery after surgery (ERAS) for colon cancer in older patients. METHODS: One hundred and fifty-nine patients enrolled in the ERAS group of our previous clinical study were divided according to age into an older group (n = 31; ≥80 years old) and a younger group (n = 128; <80 years old). We compared the two groups for clinical outcomes, including surgical complications, re-admission rates, and the time to discharge, based on criteria for hospital discharge. Compliance with each ERAS element was compared between groups. RESULTS: Concomitant diseases were present in all older patients (100%), but only in 57.8% of the younger group (P < 0.0001). The preoperative risk grade according to the American Society of Anesthesiologists classification was significantly higher in the older group than in the younger group. The postoperative surgical complications and re-admission rates were not significantly different between groups. Discharge criteria were met three days after the operation. The median length of hospital stay was slightly longer in the older group (9 days, range 5-15) than in the younger group (8 days, range 4-41; P = 0.061). Compliance above 80% was observed for 13 ERAS items in the older group and 14 ERAS items in the younger group; thus, compliance with the ERAS protocol was equally feasible in both groups. CONCLUSIONS: For older patients undergoing colon cancer surgery, an ERAS protocol might be feasible with a high implementation rate of the elements in the protocol.

RESUMO

A 63-year-old man was followed-up for diabetes mellitus. During follow-up, computed tomography(CT)showed dilatation of the main pancreatic duct in the tail of the pancreas. Abdominal enhanced CT revealed a 25 mm tumor in the body of the pancreas. Endoscopic ultrasound-fine needle aspiration(EUS-FNA)was performed, and the pathological diagnosis was adenocarcinoma. Therefore, based on the diagnosis of pancreatic body carcinoma, distal pancreatectomy with splenectomy was performed. The postoperative course was uneventful. Histological and immunohistochemical examination revealed that the tumor consisted of a ductal carcinoma and a neuroendocrine component. Therefore, combined pancreatic tumor (fT3N1M0, StageⅡB)was diagnosed. The patient subsequently received postoperative adjuvant chemotherapy(S-1 100mg/ day), and survived without recurrence 6 months after the operation. We report this case of combined pancreatic tumors with a review of the literature.

RESUMO

An 81-year-old woman underwent preoperative chemoradiotherapy(CRT)for advanced lower rectal cancer with vaginal invasion. However, she refused surgery and received additional radiotherapy. We detected a rectal-vaginal leak, so we performed ileostomy with double orifices and chemotherapy. As the tumor and vaginal leak increased, we performed laparoscopy- assisted abdominoperineal resection and vaginal posterior wall resection after 16 months of CRT. Although adhesion occurred due to inflammation and tumor invasion after the CRT, surgery could be performed safely. Despite the advanced age of the patient, complications did not occur, and no recurrence was observed for 66 month after the surgery. In rectal cancer, operation is usually performed until 6 to 8 weeks after CRT, but in our case, the surgery was performed after a long interval, with good results. Thus, we report the case herein.

RESUMO

We report a case of advanced sigmoid colon cancer that was resected after chemoradiation therapy(CRT)following ineffective chemotherapy. A 59-year-old woman harbored a lower abdominal tumor the size of an infant's head and was diagnosed with a huge sigmoid colon cancer with invasion to the urinary bladder and metastases to the para-aortic lymph nodes. The patient received 2 courses of modified FOLFOX6(mFOLFOX6)plus cetuximab therapy, which was assessed as ineffective; She then received CRTwith 50.4 Gy in 28 fractions plus concurrent oral S-1(100mg/day for 28 days). Tumor shrinkage in the primary lesion was achieved after CRT; total pelvic exenteration with the removal of metastatic para-aortic lymph nodes was then performed 5 months after the first diagnosis. This case of locally distant advanced colon cancer in the pelvic cavity coexisting with resectable metastatic lesions suggested that CRTmight contribute to successful local treatment after the failure of preoperative chemotherapy.

RESUMO

PURPOSE: Adjuvant oxaliplatin plus oral capecitabine (XELOX) is recommended for patients with curatively resected colon cancer. However, its safety and tolerability in Asian patients is unclear; therefore, we evaluated the safety and efficacy of adjuvant XELOX in Japanese patients with curatively resected stage III colon cancer (MCSCO-1024) and present the interim safety data. METHODS: This prospective, multi-center, open-label, single-arm phase II study recruited patients with curatively resected stage III colon cancer. The protocol was a 120-min intravenous infusion of oxaliplatin (130 mg/m2) on day 1 and oral capecitabine (2000 mg/m2/day) in two divided doses for 14 days of a 3-week cycle, for a total of eight cycles (24 weeks). The primary endpoint was the 3-year disease-free survival, and secondary endpoints were the treatment completion rate, safety profile (rate and severity of adverse events), and correlation of adverse events, such as peripheral sensory neuropathy (PSN), with the administration period of oxaliplatin, etc. RESULTS: From November 2011 to August 2014 (34 months), 196 patients were enrolled. Safety was analyzed in 190 patients. The median total doses of capecitabine and oxaliplatin were 215,586.9 and 777.2 mg/m2, respectively, while the median relative dose intensities were 82.5 and 76.0%, respectively. The overall treatment completion rate was 73.7%. The most frequent treatment-related adverse event was PSN (88.4%), while the most frequent grade ≥3 treatment-related adverse events were neutropenia (12.6%), PSN (6.3%), diarrhea (4.2%), and thrombocytopenia (4.2%). There were no treatment-related deaths. CONCLUSIONS: Adjuvant XELOX is tolerable for Japanese patients with Stage III colon cancer.

RESUMO

The patient was a 79-year-old woman, who had undergone pancreaticoduodenectomy(PD)for lower bile duct carcinoma in our hospital(pT3N0H0P0M0, fStage III ). Four years 6 months after the initial operation, abdominal CT revealed left bile duct expansion and hilar bile duct thickening. Therefore, based on the diagnosis of perihilar cholangiocarcinoma originating from the left hilar duct, we performed left lobectomy with caudate lobectomy and biliary tract reconstruction. The surgical specimen showed a tumor in the left hilar bile duct. Histopathological diagnosis of the tumor was a moderately differentiated adenocarcinoma(pT2aN0H0P0M0, fStage II ). Surgical margins were histologically negative. Since the tumor was located away from the anastomosed site of the cholangiojejunostomy, we determined that the tumor was not a recurrence but a metachronous cholangiocarcinoma. The postoperative course was uneventful. The patient survived without recurrence 2 years after the second operation. The possibility of heterochronic biliary carcinomas should be considered during follow-up evaluation. We report this case of metachronous cholangiocarcinoma that occurred 4 years 6 months after PD, with a review of the literature.

RESUMO

We report a case of advanced sigmoid colon cancer resected via laparoscopic surgery after preoperative chemotherapy. A- 55-year-old man visited our hospital with diarrhea. CTrevealed a giant tumor in the sigmoid colon, and surrounding lymph node enlargement was also noted. The tumor appeared to be locally advanced; thus, preoperative chemotherapy was started. Due to the possibility of obstruction, we constructed an ileostomy laparoscopically. The tumor was found to be RAS wild, and 4 courses of mFOLFOX6 plus panitumumab were given. Follow-up CTshowed remarkable tumor reduction allowing laparoscopic resection; as such, laparoscopic sigmoidectomy was performed successfully. Chemotherapy with molecular-targeted drugs is a promising method to make laparoscopic surgery possible for advanced colorectal cancer.

RESUMO

To elucidate ideal strategy of treatment for advanced lower rectal cancer, we investigated 11 patients with clinically suspected lateral pelvic node(LPN)metastasis among 36 patients who received neoadjuvant chemoradiation therapy(NCRT). Nodal metastasis was diagnosed as positive when the major axis of a lymph node was over 7mm in computed tomography(CT). Both tumor and nodal downstaging were observed in CT after NCRT; pathological complete response and ypN0 was obtained in 2(18.2%)and 6(54.5%)cases, respectively, and positive LPN was observed only in 2 cases. All of 4 cases who were diagnosed as ycN0 in CT after chemoradiation were confirmed as ypN0. Extended examination with 36 patients who underwent NCRT showed that 85% of 21 ycN0-cases were confirmed to be ypN0. As a conclusion, NCRT for lower rectal cancer with suspected LPN metastasis was highly effective, and omitting lateral node dissection when all nodes turned to be less than 7mm on CT, can be a hopeful option.

RESUMO

A 60-year-old man was admitted for a liver mass(S3), which rapidly increased in size during intraductal papillary mucinous neoplasm(IPMN)follow-up. Although EOB-MRIwas performed, the mass could not be accurately diagnosed as hepatic cancer. Thus, we performed a lateral segmentectomy. In the resected specimen, a solid tumor mass was clearly bound in segment 3 of the liver. Since histopathology revealed no malignant cells and many IgG4-positive cells, we confirmed the diagnosis as IgG4-related inflammatory pseudotumor of the liver. IgG4-related diseases occur in various organs in the body, and they are known to associate with autoimmune pancreatitis and sclerosing cholangitis, but an IgG4-related inflammatory pseudotumor of the liver is a rare disease. It is often difficult to distinguish from hepatic cancer and surgical resection is performed.

A 70-year-old man was referred because of suspected gallbladder cancer and gallstones. Contrast-enhanced CT, EOB-MRI and PET-CT could not completely rule out gallbladder cancer. The patient preferred follow-up without surgery. At 4 months after initial examination, the gallbladder wall thickening showed improvement, but appeared worse at 9 months after initial examination. Therefore, we decided to perform surgery. Since malignant findings were not observed on rapid intraoperative pathology, we performed a cholecystectomy and right hemicolectomy because of inflammation in the transverse colon. Pathological examination diagnosed xanthogranulomatous cholecystitis. The imaging appearance of xanthogranulomatous cholecystitis varies, and also changes over time, making it difficult to distinguish from advanced gallbladder cancer. We experienced a case of xanthogranulomatous cholecystitis that changed over time, and report this case with a review of the literature.
