A 56-year-old woman diagnosed with type 2 gastric cancer and multiple lymph node metastases(T3N3M1[lym], cStage Ⅳ)was treated with chemotherapy using trastuzumab with S-1 plus cisplatin for 6 cycles. The primary lesion showed PR, and lymph node metastases disappeared after the chemotherapy. Because of adverse events, she was administered with 2 additional cycles of trastuzumab with S-1 plus cisplatin and 6 cycles of trastuzumab with capecitabine plus oxaliplatin. However, the primary lesion increased in size. Therefore, she underwent distal gastrectomy and D1+ lymphadenectomy with para-aortic lymph node sampling as a conversion surgery. The pathological diagnosis was T2N0M0, pStage ⅠB, and the primary cancer was Grade 1a owing to the chemotherapeutic effect. She survives without recurrence or postoperative adjuvant therapies 3 years after the surgery.We present the case of a 69-year-old man who was diagnosed with ascending colon cancer. Preoperative CT revealed 2 advanced esophageal cancers, both at T4; thus, a diagnosis of esophageal cancer(Ut-Ce, cT4b[Tr]N2M0, Stage ⅣA/Mt, cT4b[Lt-Br]N2M0, Stage ⅣA)was made. The patient received chemotherapy(DTX/CDDP/5-FU), and as the second-line treatment, he received chemoradiotherapy(40 Gy with DTX/CDDP/5-FU). We performed transthoracoabdominal esophagectomy, laryngeal preservation with tracheal resection, 3-field lymph node dissection, posterior mediastinal gastric tube reconstruction, mediastinal tracheostomy, and pectoralis major myocutaneous flap filling. He had an anterior chest wall subcutaneous abscess without respiratory complications. Pathological examination indicated a complete response. Two months after the surgery for esophageal cancer, radical surgery was performed for the colon cancer. Apoptosis inhibitor Fifty-five months after esophagus cancer surgery, no recurrence was observed.A 65-year-old man visited our hospital for hepatocellular carcinoma(HCC)and underwent extended posterior sectionectomy. Eight months after the hepatic resection, follow-up computed tomography(CT)revealed a solitary, recurrent tumor in S4 of the liver, and transcatheter arterial chemoembolization and radiofrequency ablation were performed for the intrahepatic recurrence. After 12 postoperative months, follow-up CT demonstrated pulmonary metastases in S5 of the right lung and S10 of the left lung. Since there were no other metastases, the 2 metastatic lesions were resected using video-assisted thoracoscopic surgery(VATS). The resected tumors were histologically diagnosed as pulmonary metastases of HCC. Three years after the pulmonary resection, 3 additional pulmonary metastases were detected on CT in S3 and S10 of the right lung and S4 of the left lung. No other metastases were found. Bilateral VATSmetastasectomy was performed for the metastases. The tumors were diagnosed as pulmonary metastases of HCC on histological examination. One year and 8 months after the surgery, he was alive in a good condition, with no recurrences. The present case suggested that some patients with pulmonary metastasis of HCC can have long-term survival with surgical resection of the metastasis. Therefore, while systemic chemotherapy is generally considered the standard treatment for extrahepatic metastasis of HCC, surgical resection might be an option.A 74-year-old woman presented with epigastric pain. Imaging revealed a tumor measuring 80 mm, with internal necrosis, originating from the gallbladder and invading the liver. We performed extended anterior segmentectomy of the liver and lymph node resection following a preoperative diagnosis of gallbladder cancer. Histologically, the tumor was diagnosed as an undifferentiated carcinoma of the gallbladder. Although curative resection was performed, the patient developed recurrence with liver metastasis and peritoneal dissemination after 6 postoperative weeks and died after 10 postoperative weeks.Intraductal papillary mucinous neoplasm(IPMN)of the pancreas often presents with multifocal lesions. Complete resection without residual skip lesions is essential for complete eradication of the disease. We experienced a case of IPMC in which intraoperative pancreatoscopy was used to determine the surgical margin. Intraoperative pancreatoscopy is a useful and easy method to evaluate the remnant duct and exclude residual tumor. A cystic lesion was incidentally detected in the pancreatic head of a 78-year-old man. Ultrasonography, abdominal computed tomography, magnetic resonance imaging, and endoscopic ultrasound revealed enhancing mural nodules in the pancreatic head and dilation of the entire main pancreatic duct. We performed pancreaticoduodenectomy for mixed IPMN. Intraoperative pancreatoscopy, which was performed to rule out skip lesions, showed no mucosal abnormalities in the remnant duct. The pathological diagnosis was non-invasive intraductal papillary-mucinous carcinoma(IPMC). No signs of recurrence were seen for 6 postoperative months.INTRODUCTION Primary small-cell carcinomas occur commonly in the lungs but rarely in the other organs. We studied the treatment outcomes in 6 cases of primary small-cell carcinoma of the digestive tract at our hospital. PATIENTS Six patients were diagnosed with small-cell carcinoma of the digestive tract histopathologically and treated at our hospital from September 2000 to December 2018. RESULTS The average age of the patients was 61.5 years(range 40-80 years). Patients were 3 men and 3 women. The occurrence sites were the esophagus, stomach, and colon in 1, 2, and 3 patients, respectively. The patient with esophageal cancer underwent chemoradiotherapy without surgery. Other patients, except for 1 patient with colon cancer, underwent adjuvant chemotherapy after the surgery. Two of the 6 patients survived for over 5 years. DISCUSSION For small-cell carcinomas of the digestive tract with poor prognosis, long-term survival can be expected using multidisciplinary treatments depending on the case.We report a case of colorectal cancer associated with Crohn's disease in a 50-year-old man. He had been diagnosed with Crohn's disease 26 years before and had undergone sigmoidectomy for sigmoid colon stenosis 19 years before. Ileal resection, was performed for ileus stenosis 12 years before. Three years before, partial resection of the small intestine was performed for perforation of the small intestine. During this period, the medical treatment was continued, but the patient experienced remission and exacerbation. He complained of anal pain at a regular outpatient visit, and endoscopic examination showed an elevated lesion immediately above the dentate line. Adenocarcinoma Group 5 was detected on biopsy. The diagnosis was rectal cancer(cT2N3M0, StageⅢb). We performed an abdominoperineal resection, a D3 lymph node dissection, and colostomy. Chemotherapy with mFOLFOX6 was provided postoperatively. The patient has survived without recurrence for 1 year and 6 months after the surgery.
