Carbon-ion radiotherapy with chemotherapy for LAPC may improve curative resection rate.
Carbon-ion radiotherapy with chemotherapy for LAPC may improve curative resection rate.A 67-year-old woman with upper abdominal pain was referred to our hospital. Upper gastrointestinal endoscopy revealed a type 3 gastric cancer at the greater curvature of the angular notch. Abdominal CT helped detect the primary tumor. Multi-detector-row computed tomography(MDCT)and 3D-CT angiography revealed a vascular anomaly in which the left gastric and splenic arteries formed the common trunk. The common hepatic and superior mesenteric arteries formed the common trunk. We performed a laparoscopic distal gastrectomy with D2 lymph node dissection. During suprapancreatic lymph node dissection, the surface of the portal vein was difficult to expose toward the left side because the portal vein joined the splenic and superior mesenteric veins on the caudal side. Therefore, the No. 8a lymph nodes were dissected along the anterior hepatic plexus. In cases of common hepatic artery anomaly, identifying the anterior hepatic plexus is useful for the dissection of the suprapancreatic lymph nodes.The need to remove palliative primary tumors in the incurable Stage Ⅳ colorectal cancer patients remains debatable. Here, we describe the case of a 62-year-old man diagnosed with rectal cancer(cT3N2bM1b, cStage Ⅳb)with both primary tumor and metastatic lesions that were unresectable. Systemic chemotherapy was administered with 5-fluorouracil, Leucovorin, and oxaliplatin(FOLFOX)or FOLFOX with bevacizumab(BEV). After 12 months of treatment, CT scan revealed that both the primary tumor and metastases had shrunk significantly, leading to the conclusion that the primary tumor was resectable. Subsequently, laparoscopic abdominoperineal resection was performed. The patient was discharged 21 days postoperatively, and chemotherapy(FOLFOX plus BEV)was reintroduced 24 days after discharge. The patient was alive 25 months after the first consultation. Palliative primary tumor resection involves risks of operative complications and tumor progression owing to the absence of chemotherapy; however, some recent evidence has shown that primary tumor resection was associated with better prognosis and could be a good option on an individual patient basis. Further studies are required to establish the optimal strategy for patients with Stage Ⅳ colorectal cancer.Endometrial cancer(EC)is often the sentinel cancer in women with Lynch syndrome(LS), but the actual incidence of EC as the sentinel cancer in patients with LS is not well-known in Japan. We investigated the history of malignancies and incidence of sentinel cancers in patients with LS-associated EC and their relatives. We examined 8 patients with LS-associated EC between 2005 and 2019. Five of them(63%)had suffered from a cancer other than EC, while 5(63%)had developed a cancer after EC. Seven patients(88%)had EC as the sentinel cancer, while 1(13%)developed colorectal cancer before EC. Among first-degree relatives(15 men and 23 women), 15(40%)had a history of cancer, of whom 7 were women (30%). Five women(22%)had EC, all sentinel. Among second-degree relatives(40 men, 44 women, 14 unknown), 16 (16%)had cancer. Four women(9%)had a history of cancer, of whom 2(5%)had EC, all sentinel. Although we only investigated a few LS cases, the importance of EC as the sentinel cancer was highlighted in Japanese women with LS.Unresectable advanced gastric cancer is associated with poor prognosis. In a few studies, long-term survival was achieved with conversion surgery in patients who responded to chemotherapy. Here, we have reported a case of unresectable advanced gastric cancer in which curative resection was achieved with conversion surgery. A 70-year-old man who was diagnosed with advanced gastric cancer with multiple liver metastases received S-1/cisplatin therapy(S-1 120 mg/kg of bodyweight[bw]plus cisplatin 90 mg/kg of bw)as primary therapy. Because of the adverse reactions, secondary treatment with irinotecan therapy(CPT-11 200 mg/kg of bw)was initiated, which led to clinical complete response. A local recurrence was observed 44 months later; hence, irinotecan therapy was reinitiated. Although the disease was stable for 30 months, disseminated nodules appeared; thus, immunotherapy(nivolumab 150 mg/kg of bw)was initiated as tertiary treatment for the progressive disease. Although the number of disseminated nodules decreased, frequent blood infusions were necessary for anemia. Distal gastrectomy was planned as palliative surgery. Since no noncurative factors were detected intraoperatively, we considered that curative resection could be achieved with pancreaticoduodenectomy and changed the procedure. The operative time was 6 hours 35 minutes, and there was a blood loss of 312 g. The pathological diagnosis was ypT2- N1M0P0M0, ypStage ⅡA. At 13 months postoperatively, the patient was alive without recurrence.Here, we present the case of a 47-year-old woman with liver masses having distinct borders, which were located approximately 13 cm from the left hepatic lobe S4, as visualized on a CT scan. Hepatocellular carcinoma(HCC)was suspected from these contrast findings. Additionally, we found nodules in the right upper lobe of the lung and in the left apex. Although test results for hepatitis B and C viruses were negative, the α-fetoprotein(AFP)level was elevated. The tumor was diagnosed as a HCC with suspected multiple lung metastases. Thereafter, a resection was performed for the HCC. However, multiple recurrences were observed. Arterial embolization using transcatheterization was performed thrice 5 months after resection. Further, 6 months after resection, lenvatinib therapy was initiated as the pulmonary nodule increased in size. One year after the operation, a recurrent neoplastic lesion in the liver was detected on the contrast-enhanced MRI. Since the earlier treatment with transcatheter arterial embolization plity therapy including arterial injection chemotherapy is successful in treating HCC.A 72-year-old woman was admitted to the gastroenterology division of our hospital due to abdominal pain and vomiting. selleck chemical Dynamic contrast-enhanced CT showed a tumor at the body of the pancreas and main pancreatic duct dilation. She was diagnosed with carcinoma of the body of the pancreas via EUS-FNA. There was no vascular invasion or distant metastasis on preoperative imaging. She was introduced to the Gastrointestinal Surgery division where a mesenteric nodule was found at the time of the surgery. Intraoperative frozen section confirmed the diagnosis of occult peritoneal metastases. After consulting with her family, we completed the pancreatosplenectomy. On histopathological examination, this case was TS2, tub2, pT3, mpd0, S1, RP1, PV0, A0, PL0, OO0, N0, M1(PER), CY1, PCM0, DPM0, R1, stage Ⅳ. After the operation, we treated the patient with gemcitabine(GEM)plus nab-paclitaxel for 3 months(4 courses). She then developed side effects such as anorexia and tiredness. After discussing with the patient, chemotherapy was discontinued.
