We report a case of rapidly growing breast spindle cell carcinoma. The case was a 69-year-old female. Her chief complaint was right breast pain. She was being followed after surgery for left breast cancer but was seen because of right breast pain. In the right mammary gland CD area, a 27×27 mm large unclear mass lesion was observed, which had not been seen half a year prior. Right mastectomy and axillary dissection were performed following a preoperative diagnosis of pT2N1M0, pStage ⅡB ductal carcinoma. Currently, 2 years and 2 months have passed since the operation, and recurrence has not been observed. Case reports of rapidly growing breast spindle cell carcinoma are occasionally found, but no literature specifically defines acute growth. Here, we defined rapid growth using the tumor doubling time(DT)proposed by Gerstenberg et al. Of all the reported cases of breast spindle cell carcinoma, the DT was fewer than 90 days in most cases. Breast spindle cell carcinoma demonstrates rapid grown compared to normal breast cancer.

The prognosis of patients with esophageal cancer recurrence is poor, and surgical treatment is rarely performed. Here, we report on a patient with long-term survival who underwent pulmonary metastasis resection twice after curative resection of esophageal cancer. A 62-year-old male underwent curative resection of esophageal cancer after preoperative chemoradiotherapy. The histopathological diagnosis was poorly differentiated squamous cell carcinoma(pT2N1M0, fStage Ⅱ). Five months after the operation, right lung metastasis(right-S2)was detected. Accordingly, pulmonary metastasis resection was performed. Fourteen months after the initial operation, left lung metastases(left-S3/S6)were detected. The patient underwent resection again for the pulmonary metastases. The patient died of pneumonia without recurrence 8 years 3 months after the initial operation. In selected cases, surgical resection seems effective for treating distant esophageal cancer metastasis, suggesting that surgery should be an option in cases of accumulation of numerous distant metastases in esophageal cancer.

The patient was a 48-year-old woman. She consulted our hospital with a chief complaint of vomiting. Colonoscopy showed stenosis and edematous mucosa, and biopsy was performed. Histological examination demonstrated the lesion to be colonic metastasis of breast cancer, invasive lobular carcinoma. Although colorectal metastasis of breast cancer has a poor prognosis and chemotherapy is considered as the main treatment modality, hormone therapy is also a treatment option depending on the condition.

The patient was an 82-year-oldwoman. She consultedour hospital with a chief complaint of left breast mass. MRI showed enhancedtumor with skin andextensive pectoral muscle invasion, so it was unresectable. Immunohistopathological analysis revealeda HER2-positive lesion. We administerederibulin, trastuzumab andpertuzumab, after which the tumor became resectable. Histological examination revealedremarkable response. Combination therapy of eribulin, trastuzumab andpertuzumab was well toleratedandconsid eredto be effective.

An 87-year-oldwoman was admittedto our hospital with abdominal pain andfever. Computedtomography showeda 25 mm tumor mass in the pancreatic headandshowedd ilatation of the pancreatic duct andcommon bile duct. She was diagnosed with obstructive cholangitis due to pancreatic head cancer. An endoscopic naso-biliary drainage(EUS)tube was inserted, and an endoscopic ultrasound(ENBD)examination was performed. At this time, duodenal perforation occurred, and an emergency operation was performed. During the laparotomy, perforation was found in the anterior wall of the duodenum. The contamination in the abdominal cavity and the degree of tissue damage in the duodenum were mild. Gall bladder jejunal andd uodenal jejunal anastomoses were performedfor biliary bypass andto close the perforation andbypass the gastrointestinal tract, respectively. She hadno postoperative complications andwas discharged 13 days postoperatively. Oral intake was possible after discharge, andthe patient returnedhome without complications. She died 5 months postoperatively. In this case, we performedbile duct andgastrointestinal bypass surgery prophylactically. Although this surgery will not be effective for all patients, we thought that it wouldbe useful for predicting the patient's future condition and for increasing the procedural options, even in case of emergency surgery.

A 67-year-old female was diagnosed with Stage Ⅳ rectal cancer with paraaortic lymph node metastasis. The patient underwent Hartmann's operation with D3 lymph node and paraaortic lymph node dissection. Postoperative chemotherapy with FOLFIRI was then administered for 1 year. However, liver metastasis developed, for which partial hepatectomy was performed. Postoperative chemotherapy with S-1(20 courses)was then administered. Three years and 11 months following the first operation, lymph node metastases developed and resection of lymph nodes(No. 12p, No. 16b1int)was performed. Postoperative chemotherapy with capecitabine(Cape)(8 courses)was then administered. Five years and 7 months following the first operation, Virchow lymph node metastasis developed. Despite chemotherapy with Cape and bevacizumab (Bmab), Virchow lymph node swelling recurred, and resection was performed. Nine years and 4 months following the first operation, lymph node metastases developed, and resection of lymph nodes(Virchow, No. 16b1int)was performed. Postoperative chemotherapy with S-1(8 courses)was then administered. At present, 11 years and 4 months after the first operation, the patient, whose chemotherapy has been discontinued, is alive without recurrence.

Purpose: Emergency surgery for obstructive colorectal cancer is considered to be associated with a high degree of risk, and surgery may after decompression is considered to be safer. In cases of obstructive colorectal cancer, decompression can be achieved with surgery, an ileus tube, or a stent, depending on the disease condition. We herein compare the treatment methods for obstructive colorectal cancer., Methods: Forty-two patients with obstructive colorectal cancer underwent emergency treatment between January 2012 and December 2016., Results: Among the patients with obstructive colorectal cancer, 18 receiveda stent, 10 receiveda nasal ileus tube, 6 receiveda transanal ileus tube, 5 underwent stoma construction, and 3 underwent emergency surgery without decompression. The stent group showed the highest laparoscopic operation rate. There was no significant difference in the overall survival of the treatment groups. One patient in the stent group developed duplicated cancer., Conclusion: Stent placement can be considered to be a viable option in the emergency treatment for obstructive colorectal cancer because laparoscopic surgery anda preoperative examination can be performed.
