Robot-assisted distal gastrectomy and local resection for gastric cancer and gastrointestinal stromal tumor.

Gastrointestinal stromal tumors surrounding the esophagogastric junction are often challenging to resect, with no consensus regarding the optimal surgical technique. Here in, we present a case of concurrent gastric cancer in the antrum and gastrointestinal stromal tumors adjacent to the esophagogastric junction. The patient underwent simultaneous distal gastrectomy and local resection assisted by a surgical robot, avoiding the need for total gastrectomy.

[A Case of Rheumatoid Arthritis after Administration of an Aromatase Inhibitor in a Menopausal Patient with Breast Cancer].

Therapy with an aromatase inhibitor(AI)was initiated in a 91-year-old female patient after she had been diagnosed with breast cancer. One week after taking the medicine, she experienced multiple joint pain in her upper extremities. Finally, she was diagnosed with rheumatoid arthritis(RA).

Hyaline-vascular type unicentric Castleman disease with dysplastic follicular dendritic cell proliferative lesions: a case report.

Castleman disease (CD) is a rare lymphoproliferative disease. Hyaline-vascular type unicentric CD has a good prognosis if completely resected during surgery. However, follicular dendritic cell proliferative lesions have the potential for recurrence and metastasis.

[A Case of Advanced Colon Cancer with Long-Term and Re-Administration of Regorafenib].

A 54-year-old woman diagnosed with sigmoid colon cancer and multiple liver metastases underwent sigmoidectomy, partial hepatectomy, and RFA in September 2009. Because of postoperative liver and lung recurrence, 5 regimens with combinations of L-OHP/CPT-11 plus anti-VEGF antibody/anti-EGFR antibody was performed. Following these treatments, she underwent hepatic arterial infusion therapy with UFT/Krestin for progressive liver metastases.

Middle segment-preserving pancreatectomy for recurrent metastasis of renal cell carcinoma after pancreatoduodenectomy: a case report.

Many cases of surgical resection of metastatic pancreatic tumors originating from renal cell carcinoma have been reported; however, cases of reresection of recurrent pancreatic metastasis of renal cell carcinoma in the remnant pancreas are rare. We performed a second resection for recurrent pancreatic metastasis of renal cell carcinoma six years after pancreatoduodenectomy with pancreaticogastrostomy reconstruction. By performing middle segment-preserving pancreatectomy, we were able to successfully spare the exocrine and endocrine pancreatic function compared to that observed after total pancreatectomy, with no signs of recurrence for two years after the surgery.

[Prognostic factors affecting the surgical treatment of metastatic lung tumor from colorectal cancer].

For aging, people having malignant disease are increasing. And surgical resection is an important part in the treatment of pulmonary metastasis from colorectal cancer. We analyzed the treatment outcome and prognostic factors affecting survival in our subset of patients.

[A case of postoperative liver metastasis of mucinous carcinoma of the breast with complete response to sequential administration of FEC75, tamoxifen citrate, and letrozole].

A 51-year-old woman, who had undergone mastectomy due to a mucinous carcinoma of her left breast, was diagnosed with solitary liver metastasis 7 months after operation. Systemic chemotherapy consisting of 5 courses of FEC75 (cyclophosphamide 500 mg/m2, epirubicin 75 mg/m2, and 5-FU 500 mg/m2 on 1st day, with 1 course for 21 days) was followed by sequential hormonal therapy with tamoxifen citrate and letrozole. The size of metastatic lesions on CT gradually reduced, and FDG-PET, which was conducted 4 months after initiation of FEC75, showed no viable tumor cells in the target lesion.

[Advanced rectal cancer in an older patient, in whom metastatic liver lesions were effectively controlled with oral UFT+LV and venous CPT-11 administration--case report].

An 81-year-old man was admitted to our department due to acute ileus. He was diagnosed with sigmoid colon cancer with multiple metastatic lesions in the right lobe of the liver. Two weeks after insertion of an ileus tube, he underwent sigmoidectomy and permanent colostomy.

Fibroepithelioma-like changes occurring in perianal Paget's disease with rectal mucinous carcinoma: case report and review of 49 cases of extramammary Paget's disease.

Background: Anogenital Paget's disease (PD) may be accompanied by varying degrees of epidermal hyperplasia. The histological changes can be reminiscent of fibroepithelioma of Pinkus.

Methods: We present a case of perianal PD associated with fibroepitheliomatous epidermal hyperplasia in a 76-year-old-man with an underlying rectal mucinous carcinoma.
