RESUMEN
The patient was a 61-year-old man with a diagnosis of carcinoma of the pancreatic head. Abdominal computed tomography( CT)showed no distant metastasis, and he underwent subtotal stomach-preserving pancreatoduodenectomy. Immediately after surgery, he received liver perfusion chemotherapy with 5-fluorouracil followed by systemic gemcitabine. Eighteen months after surgery, CT revealed liver metastasis in the S6 segment, and partial hepatectomy was performed. The pathological diagnosis was liver metastasis of pancreatic cancer. Postoperatively, the patient was treated with gemcitabine and S-1 therapy for 1 year and then switched to S-1 monotherapy for about 6 months. Four years after the initial surgery, CT showed 2 metastases in the right lung. After 2 months of S-1 monotherapy, wedge resection of the upper and lower lobes of the right lung was performed. Gemcitabine and nab-paclitaxel therapy were administered, after the metastasectomy, but pleural dissemination appeared on CT 5 years after the initial surgery. Modified FOLFIRINOX therapy was started and continued for 8 months, but CT revealed further disseminated lesions in the diaphragm. Palliative irradiation was provided, but the disease gradually progressed. After multidisciplinary treatment, the patient survived for 6 years and 3 months after the initial surgery.

BACKGROUND: The definition and classification of regional nodes are not standardized for perihilar cholangiocarcinoma. This study aimed to clarify the rational extent of regional lymphadenectomy and to elucidate the impact of number-based regional nodal classification on survival of patients with this disease. METHODS: Data of 136 patients with perihilar cholangiocarcinoma who underwent surgery were reviewed. The incidence of metastasis and the survival of patients with metastasis were calculated for each node group. RESULTS: The incidence of metastasis for the node groups in the hepatoduodenal ligament (denoted as no. 12) ranged from 3.7% to 25.4%, with 5-year disease-specific survival of 12.9% to 33.3% for patients with metastasis. The incidences of metastasis in the common hepatic artery (no. 8) and posterior superior pancreaticoduodenal (no. 13a) node groups were 14.4% and 11.2%, respectively, with 5-year disease-specific survival rates of 16.7% and 20.0% for the patients with metastasis. When these node groups were defined as regional nodes, the 5-year disease-specific survival rates for the patients with pN0 (n = 80), pN1 (1-3 positive nodes, n = 38), and pN2 (≥ 4 positive nodes, n = 18) were 61.4%, 22.9%, and 17.6%, respectively (p < 0.001). The pN classification was independently associated with disease-specific survival (p < 0.001). When only the no. 12 node groups were regarded as regional nodes, pN classification failed to stratify the patients prognostically. CONCLUSIONS: No. 8 and no. 13a node groups should be considered regional nodes in addition to no. 12 node groups and should be dissected. The number-based regional nodal classification allows patients with this disease to be stratified prognostically.

We report a case of intrahepatic cholangiocarcinoma(ICC)with lymph node metastases in which long-term survival was achieved after surgery followed by chemotherapy. A 69-year-old man underwent left hepatectomy, extrahepatic bile duct resection, and lymph node dissection for ICC located mainly in segment 4 of the liver with enlarged lymph nodes in the hepatoduodenal ligament. The histopathologically confirmed diagnosis was ICC(T2N1M0, Stage â £A)with 3 positive lymph nodes(No. 12a1, No. 12p1, and No. 12p2). He received chemotherapy with gemcitabine(GEM)plus cisplatin(CDDP)for 9 months, followed by GEM monotherapy for 4 months, and then S-1 monotherapy was started. A right lung nodule was detected 12 months after the initiation of S-1 monotherapy. He received GEM plus S-1 therapy for 28 months, followed by S-1 monotherapy, leading to disappearance of the lung nodule. He remains alive and well without disease 78 months after surgery. Our experience in this case suggests that radical resection followed by chemotherapy may provide a survival benefit in selected patients who have ICC with nodal disease.

An 87-year-old woman with a gradually enlarging mass in her left breast, diagnosed as having left-sided breast cancer with skin invasion by a local practitioner, was referred to our hospital. Computed tomography revealed ascending colon cancer with abdominal wall invasion and a thoracic aortic aneurysm(Stanford type B), in addition to breast cancer with skin invasion. A thoracic endovascular aortic repair and bypass surgery between the subclavian arteries were both performed for the thoracic aortic aneurysm. After 6 days, a right hemicolectomy and D2 lymphadenectomy were performed for the ascending colon cancer. A postoperative pathological diagnosis of pT3N0M0, pStage â ¡a, was made. A total left mastectomy with a full-thickness skin graft for left breast cancer was performed after 2 months following the ascending colon cancer surgery. The postoperative pathological diagnosis was pT3N0M0, pStage â ¡B. No evidence of local recurrence or distant metastasis of the ascending colon cancer has been observed at 20 months postoperatively, or of the breast cancer after 18 months following surgery.

A 75-year-old woman presented to our hospital with abdominal pain and melena. Colonoscopy revealed an ulcer at the appendiceal orifice. Histopathological examination of biopsy specimens revealed adenocarcinoma. Computed tomography showed an appendiceal mass of 11.8×6.7 cm in size involving the cecum and terminal ileum without any distant metastatic findings. Ileocecal resection with regional lymph node dissection to the root of the ileocolonic artery was performed. Histopathological examination of the specimen revealed appendiceal adenocarcinoma. Molecular subtype of the tumor was BRAF V600E mutation and microsatellite instability-high(MSI-H). The pathological stage was pT4bpN1bcM0, pStage â ¢C. She received 8 courses of CapeOX as adjuvant chemotherapy and no recurrence was noted 12 months following the surgery. The establishment of standard treatment strategies including surgery, chemotherapy, and immunotherapy for carcinoma of the appendix with BRAF V600E mutation and/or MSI-H is needed.

A 66-year-old man was referred to our hospital with fever and abdominal pain. CT showed a mass in the intrapancreatic bile duct but no wall thickness in the perihilar bile ducts. Neither regional lymphadenopathy nor distant metastasis was observed. Biliary cytology showed adenocarcinoma. The diagnosis was distal cholangiocarcinoma, and pancreatoduodenectomy was performed. Intraoperative frozen section examination of the ductal resection margins at the right and left hepatic ducts was positive for carcinoma in situ, and the operation ultimately completed with R1 resection. Histological examination confirmed a diagnosis of cholangiocarcinoma with superficial spread and a single positive lymph node. Adjuvant chemotherapy with S-1 was administered for 1 year. Anastomotic recurrence at the hepaticojejunostomy was found 5 years after resection; biopsy specimens revealed adenocarcinoma. Thereafter, S-1 chemotherapy was resumed, and the patient remains alive and well 9 years and 1 month after resection.

A 58-year-old woman presented with a complaint of weight loss. Abdominal computed tomography showed dilatation of the biliary and pancreatic ducts and a mural nodule in the pancreatic duct. The diagnosis was intraductal papillary mucinous neoplasm(IPMN). Endoscopic retrograde cholangiopancreatography(ERCP)and cholangioscopy revealed a fistula between the common bile duct and the IPMN. A sudden increase in hepatobiliary enzymes was noted preoperatively. ERCP showed that the common bile duct was obstructed by mucus. A nasobiliary drainage tube was inserted into the bile duct endoscopically and kept open by daily tube washing, and the liver dysfunction improved. Total pancreatectomy, splenectomy, and regional lymph node dissection were performed. Histological examination confirmed that the primary tumor was mixed invasive intraductal papillary mucinous adenocarcinoma. The patient remains alive and well with no evidence of recurrence 18 months after resection.

We report a case of biliary cystadenocarcinoma in which long-term survival was achieved after 2 operations for intrahepatic recurrence. A 72-year-old man with biliary cystadenocarcinoma located mainly in segment 3 of the liver underwent left hepatectomy, extrahepatic bile duct resection, and lymph node dissection. Seven years and 9 months after the initial resection, he underwent partial liver resection(segment 5)for intrahepatic recurrence detected by computed tomography. Fifteen years and 7 months after the initial resection, he underwent repeat partial resection of the liver(segment 5)for intrahepatic recurrence. Histologically, these tumors were confirmed to be recurrence of biliary cystadenocarcinoma. He remains alive and well with no further recurrence 21 years and 6 months after the initial resection. This case and a literature review suggest that hepatic resection is a useful treatment option for intrahepatic recurrence of biliary cystadenocarcinoma.

A 57-year-old man was diagnosed as having resectable advanced esophageal carcinoma adjacent to the trachea(Ut, cT3N0M0)and received preoperative docetaxel, cisplatin, and 5-fluorouracil therapy. Due to tracheal tumor invasion and upstaging to cT4bN0M0 after 1 course of chemotherapy, the treatment was converted to definitive chemoradiotherapy (CRT). A remarkable response with no evidence of tracheal invasion was observed on computed tomography following definitive CRT. He underwent successful curative resection with salvage esophagectomy, and the resected tumor was staged as pT1bN0M0. No adjuvant therapy was administered, and the patient was alive with no evidence of disease at the 5-year postoperative follow-up. The response to preoperative treatment should be meticulously assessed and appropriate treatment modalities used to avoid overlooking the potential for cure, even if the response to preoperative treatment with docetaxel, cisplatin, and 5-fluorouracil is poor.

A 71-year-old man with middle thoracic esophageal cancer was treated with neoadjuvant chemotherapy using docetaxel plus 5-FU plus cisplatin therapy and was also administered pegfilgrastim. Blood tests showed elevated white blood cell counts and C-reactive protein levels before the start of the third course. Contrast-enhanced computed tomography revealed wall thickening of the aortic arch. We diagnosed this as aortitis due to pegfilgrastim. Inflammation was improved with conservative treatment. We then performed video-assisted thoracoscopic esophagectomy. Drug-induced vasculitis should be included in the differential diagnosis of patients with elevated inflammation markers of unknown cause following the administration of granulocyte colony-stimulating factor preparations.

A woman in her 60s had been aware of perianal erosions for 1 month. Skin biopsy showed Paget's cells in the stratified squamous epithelium, and immunohistochemistry showed negative staining for CK7 and positive staining for CK20. Colonoscopy revealed well-differentiated adenocarcinoma in the anal canal. Computed tomography showed neither regional lymph node metastasis nor distant metastasis. Hence, she was diagnosed with anal canal carcinoma with pagetoid spread. We determined the extent of resection of the skin lesion preoperatively by mapping biopsy, and performed laparoscopic abdominoperineal resection. The pathological findings revealed adenocarcinoma(tub1, tub2), and the skin resection margin was negative. Immunohistochemistry for Paget's cells in the stratified squamous epithelium showed negative staining for GCDFP-15 and CK7, and positive staining for CK20. Twenty-four months after surgery, we detected right inguinal lymph node metastasis and performed right inguinal lymphadenectomy. As of 4 months after the lymphadenectomy, no local recurrence or distant metastasis has been detected during follow-up examinations.

A 74-year-old man presented to our hospital with a mass in the left supraclavicular fossa. He was diagnosed with advanced gastric cancer with liver metastasis and left supraclavicular and para-aortic lymph node metastasis, cT3N2M1 (LYM, HEP), cStage â £(the Union for International Cancer Control, TNM 7th edition). He received a total of 3 courses of S- 1 plus cisplatin therapy. Since he developed adverse reactions such as anorexia, renal dysfunction, and thrombocytopenia and the tumor was HER2-positive, he received 25 courses of capecitabine, cisplatin, and trastuzumab chemotherapy. Three years and 2 months after the first chemotherapy, remarkable tumor reduction was observed. The patient then underwent radical distal gastrectomy with D2 lymphadenectomy, and R0 resection was achieved. The histopathological diagnosis was ypT1aN0M0, ypStage â A. Chemotherapy with trastuzumab may improve the long-term prognosis of HER2-positive Stage â £ gastric cancer if the disease is controlled and radical resection can be achieved.

The patient was a 71-year-old man with a diagnosis of duodenal carcinoma. Abdominal computed tomography(CT) showed no distant metastasis, and he underwent subtotal stomach-preserving pancreaticoduodenectomy. Postoperative adjuvant chemotherapy was not administered. A left supraclavicular lymph node recurrence was detected on CT 15 months after surgery. Capecitabine and oxaliplatin(CAPOX)therapy was administered and the metastatic lesion shrank. Positron emission tomography(PET)-CT showed no lesions at other sites and left cervical lymph node dissection was performed 5 months after the recurrence. Postoperative adjuvant therapy with S-1 was administered for 6 months. However, 2 years and 10 months after the first recurrence, CT showed recurrence in the left supraclavicular lymph node. CAPOX therapy was resumed, but due to an allergic reaction to oxaliplatin, the patient was treated with capecitabine alone. The recurrent lesion was gradually increased in size, and FOLFIRI therapy was introduced. One year and 5 months after secondary recurrence, PET-CT showed that the second recurrent lesion had grown but was confined to the left supraclavicular lymph node, so radiation therapy(60 Gy)to the left neck was performed. The disease was stable for about 10 months and chemotherapy could be discontinued. The lesion increased in size thereafter, and the patient died 7 years after initial surgery.

PURPOSE: This study aimed to elucidate the impact of anatomic location of residual disease (RD) after initial cholecystectomy on survival following re-resection of incidental gallbladder cancer (IGBC). METHODS: Patients with pT2 or pT3 gallbladder cancer (36 with IGBC and 171 with non-IGBC) who underwent resection were analyzed. Patients with IGBC were classified as follows according to the anatomic location of RD after initial cholecystectomy: no RD (group 1); RD in the gallbladder bed, stump of the cystic duct, and/or regional lymph nodes (group 2); and RD in the extrahepatic bile duct and/or distant sites (group 3). RESULTS: Timing of resection (IGBC vs. non-IGBC) did not affect survival in either multivariate or propensity score matching analysis. RD was found in 16 (44.4%) of the 36 patients with IGBC; R0 resection following re-resection was achieved in 32 patients (88.9%). Overall survival (OS) following re-resection was worse in group 3 (n = 7; 5-year OS, 14.3%) than in group 2 (n = 9; 5-year OS, 55.6%) (p = 0.035) or in group 1 (n = 20; 5-year OS, 88.7%) (p < 0.001). There was no survival difference between groups 1 and 2 (p = 0.256). Anatomic location of RD was independently associated with OS (group 2, HR 2.425, p = 0.223; group 3, HR 9.627, p = 0.024). CONCLUSION: The anatomic location of RD independently predicts survival following re-resection, which is effective for locoregional disease control in IGBC, similar to resection for non-IGBC. Not all patients with RD have poor survival following re-resection for IGBC.

PURPOSE: Outcomes following surgery for advanced gallbladder carcinoma remain unsatisfactory. This study aimed to determine the surgical outcome and effectiveness of adjuvant chemotherapy according to TNM stage in patients with gallbladder carcinoma. METHODS: A total of 200 patients undergoing surgery for gallbladder carcinoma were enrolled. Clinicopathological data were evaluated and surgical outcomes were compared between patients with and without adjuvant chemotherapy according to TNM stage. RESULTS: The 5-year overall survival (OS) after resection for patients with stage I (n = 27), IIA (n = 18), IIB (n = 28), IIIA (n = 25), IIIB (n = 43), IVA (n = 7), and IVB (n = 52) disease was 90.8%, 94.4%, 73.6%, 33.7%, 57.7%, 14.3%, and 11.8%, respectively (p < 0.001). R0 resection was performed in all patients with stage I or II disease, in 89.7% of those with stage III disease, and 69.5% of those with stage IV disease. For patients with stage III disease, adjuvant chemotherapy was associated with improved OS (5-year OS, 60.9% vs. 41.1%; p = 0.028) and was an independent prognostic factor (hazard ratio, 2.045; p = 0.039). For patients with stage IV disease, adjuvant chemotherapy appeared to affect OS (5-year OS, 25.1% vs. 5.3%; p = 0.041); R0 resection (hazard ratio, 1.882; p = 0.040) was the only independent prognostic factor. CONCLUSION: TNM stage clearly predicts survival after resection of gallbladder carcinoma. R0 resection with adjuvant chemotherapy is recommended for long-term survival in the multimodal management of patients with stage III or IV gallbladder carcinoma.

BACKGROUND: This study aimed to investigate the impact of surgery on outcomes in patients with recurrent biliary tract cancer (BTC) and elucidate factors affecting survival after surgery for this disease. METHODS: A single-center study was undertaken in 178 patients with recurrent BTC, of whom 24 underwent surgery for recurrence, 85 received chemotherapy, and 69 received best supportive care. Then, we carried out a multicenter study in 52 patients undergoing surgery for recurrent BTC (gallbladder cancer, 39%; distal cholangiocarcinoma, 27%; perihilar cholangiocarcinoma, 21%; intrahepatic cholangiocarcinoma, 13%). RESULTS: In the single-center study, 3-year survival after recurrence was 53% in patients who underwent surgery, 4% in those who received chemotherapy, and 0% in those who received best supportive care (p < 0.001). Surgery was an independently prognostic factor (p < 0.001). In the multicenter series, the respective 3-year and 5-year survival after surgery for recurrence was 50% and 29% in the 52 patients. Initial site of recurrence was the only independent prognostic factor (p = 0.019). Five-year survival after surgery for recurrence in patients with single distant, multifocal distant, and locoregional recurrence was 51%, 0%, and 0%, respectively (p = 0.002). Sites of single distant recurrence included the liver (n = 13, 54%), distant lymph nodes (all from gallbladder cancer, n = 7, 29%), lung (n = 2, 9%), peritoneum (n = 1, 4%), and abdominal wall (n = 1, 4%). CONCLUSION: Surgery may be an effective option for patients with less aggressive tumor biology characterized by single distant recurrence in recurrent BTC.

The patient was a 64-year-old man with diagnosis of pancreatic head cancer. Initially, abdominal CT showed pancreatic head tumor with bile duct invasion and no distant metastases including para-aortic lymph nodes(PALN). Although, subtotal stomach-preserving pancreatoduodenectomy(SSPPD)and PALN sampling was performed, intraoperative frozen section examination revealed PALN metastasis. He had chronic kidney disease and was unsuitable for standard chemotherapy, SSPPD and PALN dissection was performed instead of standard chemotherapy. Histopathological examination of the resected specimens revealed invasive ductal carcinoma in the pancreatic head region and 11 nodes out of the 17 dissected PALN. Adjuvant chemotherapy with S-1 was performed. 22 months after surgery, intraabdominal lymph nodes metastasis and lung metastasis was found. 24 months after surgery, palliative radiation therapy at a dose of 40 Gy was performed. Systemic chemotherapy with gemcitabine alone was performed, but he was dead 67 months after the initial therapy.

A 62-year-old man was incidentally found to have a pancreatic tumor by CT. He was diagnosed with pancreatic cancer by EUS-FNAB. Gemcitabine(GEM)plus nab-paclitaxel(PTX)was started as neoadjuvant chemotherapy(NAC)for resectable pancreatic cancer. However, after the end of the second course, the tumor grew rapidly and invaded the stomach, so NAC was discontinued, and surgery was performed. The pathological diagnosis was anaplastic ductal carcinoma of the pleomorphic cell type, and the histological response was Grade 1a. Multiple liver metastases appeared during adjuvant chemotherapy with S-1, so GEM plus nab-PTX and modified FOLFIRINOX were administered, but the therapeutic response was poor, the patient died 9 months after surgery. Anaplastic carcinoma has a poor response to chemotherapy and may be included with cancers showing treatment resistance to NAC, as seen in our case. It is necessary to pay attention to anaplastic carcinoma during the course of NAC for pancreatic cancer.

A 70-year-old female with liver metastases from gastrointestinal stromal tumor(GIST)that were found 3 months after partial gastrectomy for the primary GIST underwent Auchincloss operation for left breast cancer with ipsilateral axillary lymph node metastases. The diagnosis was microinvasive ductal cancer that was pT1miN1M0, pStage â ¡A, hormone receptor negative, and HER2 positive. Given the impact of this cancer on the prognosis of liver metastases of GIST, imatinib therapy, but not adjuvant chemotherapy, was started promptly for breast cancer after surgery. Four months after the surgery, left subclavian lymph node recurrence of breast cancer was found. Since the liver metastases of GIST had been stable, imatinib was discontinued, and paclitaxel and anti-HER2 therapy were administered. After confirming tolerability, imatinib was carefully added in combination. Because the lymph nodes shrank and liver metastases of GIST were stable, both anti-HER2 therapy and imatinib were continued. There are few reports of combined chemotherapy for synchronous double cancer, and we report our experience in which careful treatment was required.

A 72-year-old man had a chief complaint of anal pain and difficulty in defecation. He was diagnosed with adenocarcinoma by biopsy from a tumor of the anal canal. A computed tomography scan revealed neither regional lymph node metastasis nor distant metastasis. Hence, he was diagnosed with cT3N0M0, cStage â ¡a anal canal cancer. Preoperative capecitabine- based chemoradiotherapy(CRT)(50.4 Gy in 28 fractions of 1.8 Gy each)was implemented. Digital rectal examination and imaging evaluation 8 weeks after preoperative CRT revealed that the tumor had shrunk. Fifteen weeks after preoperative CRT, laparoscopic abdominoperineal resection was performed. The pathological findings showed mucinous adenocarcinoma associated with anal fistula. At present, 12 months after the operation, no local recurrence and distant metastasis has been detected under follow-up evaluations.
