[A Case of Primary Jejunal Cancer Treated with Laparoscopic Jejunectomy with Appearance of Ileus].

An 83-year-old man visited our hospital for vomiting. Chest-abdominal computed tomography(CT)revealed that a tumor whose inside was imaged in the jejunum about 15 cm after leaving the Treitz ligament was pointed out, and dilation of the oral intestinal tract of the tumor was observed. Upper gastrointestinal endoscopy showed a type 3 circumferential tumor at the jejunum. He was diagnosed with obstructive ileus due to jejunal cancer. Laparoscopic-assisted partial jejunal resection was performed. Although the patient was followed up without chemotherapy, CT showed multiple lung and liver metastases and a mass lesion was found in the right entire chest, and a biopsy revealed skin metastasis 6 months after the operation. The patient is being followed up 10 months after surgery, there is no progression of liver, lung, and skin metastasis.

[A Case of Advanced Rectal Cancer with the Metastatic Abdominal Aortic Bifurcation Lymph Node Performed by Laparoscopic Surgery after Chemotherapy].

A 63-year-old underwent examination for constipation and was found to have an unresectable advanced rectal cancer. Metastatic abdominal aortic bifurcation lymph node and lung metastasis were suspected upon CT(cT3N3M1a[PUL1], cStage Ⅳa), and chemotherapy was administered(CapeOX plus Bmab). After 4 courses of chemotherapy, the size of the primary tumor and the lymph nodes decreased(PR). We performed laparoscopic rectum resection and abdominal aortic bifurcation lymph node. The pathological diagnosis indicated partial response(residual cancer cells)(Grade 1a). After 4 courses of chemotherapy(CapeOX), we performed pulmonary partial resection for metastatic lung cancer. This case suggests that laparoscopic resection of rectum after chemotherapy with CapeOX plus Bmab for locally advanced rectal cancer is a potential- ly effective procedure.

[Locally Advanced Breast Cancer Successfully Treated with Abemaciclib and Fulvestrant-A Case Report].

A 78-year-old woman visited our hospital for a tumor in her left breast with discharge. The 10 cm tumor had ulceration and foul smell. Scirrhous breast carcinoma was diagnosed based on core-needle biopsy findings. Chest and abdominal computed tomography( CT) revealed the tumor invading the pectoralis major muscle and a large number of swollen lymph nodes from the left axilla to the subclavian region, but no distant metastases. After 6 months of locally advanced breast cancer treatment with abemaciclib and fulvestrant, ulceration improved. CT revealed that the tumor and lymph nodes tended to shrink. Left mastectomy with axillary lymph node dissection and combined resection of pectoralis major muscle was performed. Postoperative pathological histology revealed ypT2, ypN0, ypM0, ypStage ⅡA. Subsequently, abemaciclib plus fulvestrant therapy was continued as an adjuvant therapy. The patient has survived without recurrence 6 months after the operation. We report a case of locally advanced breast cancer in which abemaciclib and fulvestrant were effective.

[Palliative Laparoscopic Operation for an Extremely Elderly Patient with Cecum Cancer].

Symptomatic colorectal cancer in extremely elderly patients is difficult to treat. A 97-year-old woman was initially suspected of having appendicitis because of worsening right lower abdominal pain with persistent fatigue. After antimicrobial therapy, advanced cecum cancer with lymph node involvement was found. Palliative laparoscopy-assisted ileocecal resection without radical lymph node dissection was performed to prevent further inflammation. The patient was transferred to another hospital for rehabilitation on postoperative day 24, when she regained walking function. This palliative procedure can be an effective treatment for elderly patients with symptomatic advanced colon cancer.

[A Case of Laparoscopic Surgery for Advanced Rectal Cancer with Lateral Lymph Node Metastasis Resected after Neoadjuvant Chemotherapy].

A 62-year-old man with diarrhea and metastases was found to harbor 2 rectal cancers. Both lateral lymph nodes were suspected based on CT and PET-CT(cT3N3M0, cStage Ⅲb). We planned to administer neoadjuvant chemotherapy(NAC) (CapeOX plus Bmab). After 4 courses of NAC, the sizes of both the primary tumor and lymph nodes decreased(partial response: PR). We performed laparoscopic abdominoperineal resection of the rectum(APR)with dissection of both lateral lymph nodes. The therapeutic effect was PR(few residual cancer cells)(Grade 2). After 4 courses of adjuvant chemotherapy (CapeOX), there have been no signs of recurrence for 8 months. This case suggests that laparoscopic APR after NAC with CapeOX plus Bmab for locally advanced rectal cancer is a potentially effective procedure.

[A Case of Ascending Colon Cancer with Intestinal Malformation Treated via Laparoscopic Surgery].

A 66-year-old man attended a health check-up after a positive fecal occult blood test. Colonoscopy revealed a 2 cm type 2 lesion near the ascending colon and the upper lip ofBauhin 's valve. Contrast-enhanced computed tomography ofthe abdominal region revealed aplasia ofthe ligament ofTreitz, with the duodenum running through the center. Three-dimensional vascular construction revealed intestinal malrotation, in which the superior mesenteric artery was present on the right side of the superior mesenteric vein. A diagnosis ofascending colon cancer(T2N0M0, cStage I )was made, and a laparoscopic ileocecal resection was performed. The ascending colon was not fixed to the abdominal wall, and the colon was widely depressed within the pelvis. Because no adhesion was noted, vascular processing was performed after converting to extracorporeal manipulation via a small incision in the umbilical region. The controlling vessel was the ileocolic artery, and D2 dissection was performed. The patient suffered no postoperative complications and was discharged on hospital day 13. Most reports ofintestinal malrotation concern pediatric patients, and reports ofadult cases are relatively rare. The intestinal malrotation was confirmed intraoperatively, and the procedure was performed safely. This suggests that if intestinal malrotation can be confirmed, laparoscopic surgery can be safely performed.

[A case of metastatic gastric cancer originating from transverse colon cancer].

Metastatic gastric cancer is uncommon, and metastasis of colorectal cancer to the stomach is extremely rare. We report a case of metastatic gastric cancer that originated from transverse colon cancer. A 52-year-old woman underwent a left hemicolectomy and D3 lymph node dissection based on a diagnosis of transverse colon cancer. The pathology results were as follows: mucinous adenocarcinoma, type 2, 6 × 11 cm, ss, ly1 v1, pm (-), dm (-), n1 (+), P0, H0, M0, Stage IIIa. The patient received XELOX as postoperative adjuvant therapy for 6 months. One year and 3 months after the left hemicolectomy, gastroscopy revealed a submucosal tumor in the lower body of the stomach and an incipient cancer in the cardia of the stomach, and a colonoscopy revealed an incipient cancer in the transverse colon. An endoscopic ultrasonography fine needle aspiration biopsy of the submucosal tumor in the lower body of the stomach was performed. Histology showed that this tumor was a mucinous adenocarcinoma similar to the primary transverse colon cancer, which led to a diagnosis of metastatic gastric cancer originating from transverse colon cancer. Distant metastasis was not detected. Endoscopic submucosal dissection of the incipient gastric cancer was performed, as were distal gastrectomy and partial colectomy. Peritoneal dissemination and para-aortic lymph node recurrence were detected 7 months after the second surgery.

[A case of primary carcinoma associated with anal fistula].

A 47-year-old man with no history of anal fistula was admitted to our hospital with a complaint of perianal pain. Computed tomography (CT) imaging revealed perianal abscess. Incision and drainage were performed under spinal anesthesia. Ten months after drainage, magnetic resonance imaging revealed anal fistula on the left side of the anus. Subsequently, core-out and seton procedures were performed for ischiorectalis type III anal fistula. Pathological examination of the resected specimen of anal fistula revealed a moderately differentiated adenocarcinoma, leading to the diagnosis of carcinoma associated with anal fistula. No distant metastases or enlarged lymph nodes were observed on positron emission tomography (PET)/CT. We performed abdominoperineal resection with wide resection of ischiorectalis fat tissue. The pathology results were tub2, A, ly0, v0, n0, PM0, DM0, RM0, H0, P0, M0, Stage II. Negative pressure wound therapy was performed for perineum deficiency, after which rapid wound healing was observed. Left inguinal lymph node recurrence was detected 8 months after surgery, for which radiotherapy was administered. Distant metastasis was detected 11 months after surgery. The patient died 21 months after surgery.

A foreign body granuloma after gastric perforation mimicking peritoneal dissemination of gastric cancer: report of a case.

This report presents the case of a 58-year-old man who was found to have foreign body granulomas (FBGs) that mimicked disseminated gastric cancer. The patient presented with a severe attack of acute upper abdominal pain, was admitted to the hospital, and thereafter underwent an immediate laparotomy due to a diagnosis of an upper gastrointestinal perforation. Follow-up endoscopy revealed an ulcer scar measuring 2 cm in size in the anterior wall of the middle stomach. The pathological examination of biopsy specimens taken around the scar revealed well to poorly differentiated adenocarcinoma. At the time of reoperation performed 2 months after the first operation, many small white granulomas were observed which were thought to be the result of peritoneal dissemination of the gastric cancer. However, both the cytology of the Douglas washing and pathological examination of frozen section specimens were negative for carcinoma, and therefore a distal gastrectomy was performed. The pathological examination revealed the presence of FBGs. In this rare case, the FBGs formed shortly after surgery and were difficult to distinguish from disseminated cancer.

[Super-elderly colon cancer with peritoneal dissemination effectively treated with modified FOLFOX6 chemotherapy--report of a case].

We reported a case of super-elderly colon cancer with peritoneal dissemination effectively treated with modified FOLFOX6 chemotherapy. A 80-year-old woman was referred to our hospital for abdominal distension in January 2007. Abdominal CT showed peritoneal dissemination and colonoscopy revealed transverse colon cancer. The patient's performance status (PS) score was 3. She had pleural effusion on the left side and massive acsites. After the general condition was improved, operation was performed for sub-ileus in March, but it became a probe laparotomy for severe peritoneal dissemination. We tried modified FOLFOX6 chemotherapy from April. The patient's pleural effusion decreased after 3 courses of chemotherapy and we could remove the thoracic tube. Massive acsites observed in abdominal CT disappeared after 5 courses of chemotherapy. The patient did not suffer from sub-ileus after around 8 courses of chemotherapy and she could then take food. The patient's PS score became 1, and she was discharged in September. Two more courses of chemotherapy were given on as an outpatient basis. The chemotherapy was changed to S-1 on the patient's request in November. As of February 2008, the patient's PS score was 0, and she has been under treatment as an outpatient.

Whole-body MRI for detecting metastatic bone tumor: diagnostic value of diffusion-weighted images.

PURPOSE: We assessed the diagnostic value of whole body magnetic resonance (MR) imaging (WB-MRI) using diffusion-weighted images (DWI) for detecting bone metastasis and compared it with that of skeletal scintigraphy (SS). MATERIALS AND METHODS: Thirty patients with malignancies (breast cancer, 17 patients; prostate cancer, 9; and one patient each, thyroid cancer, liposarcoma, leiomyosarcoma, and extraskeletal Ewing sarcoma) underwent both WB-MRI and SS to detect bone metastasis. All patients were followed more than 6 months by MR imaging, SS, or computed tomographic (CT) examination. For WB-MRI, patients were placed in feet-first supine position with table-top extender and quadrature body coil. We acquired DWI (axial plane from lower neck to proximal femur) (single shot short TI inversion-recovery [STIR]: repetition time [TR] 6243/echo time [TE] 59/inversion time [TI] 180 ms; b value: 600 s/mm(2); 5-mm slice thickness; 112 x 112 matrix), T(1)-weighted fast spin echo (T(1)WI), and STIR (sagittal plane of total spine images and coronal plane of whole body images) images. Four blinded readers independently and separately interpreted images of combined MR sequences of T(1)WI+STIR (session 1) and T(1)WI+STIR+DWI (session 2). RESULTS: In 10 of 30 patients, we detected a total of 52 metastatic bone lesions; in the other 20, follow-up examinations confirmed no metastatic bone lesions. For these 52 lesions, for session 2, the mean sensitivity was 96% and the positive predictive value (PPV) was 98%. Those values were superior to those of session 1 (sensitivity: 88%; PPV: 95%) and those of SS (sensitivity: 96%; PPV: 94%). CONCLUSION: WB-MRI that included DWI was useful for detecting bone metastasis.

[Complete response to CPT-11 and UFT/LV combination therapy in a case with simultaneous multiple lung metastases from colon cancer].

We report the complete response for one year of a patient with simultaneous multiple lung metastases from colon cancer who was treated using a combination of irinotecan (CPT-11) and uracil/tegafur (UFT)/Leucovorin (LV) using a schedule reported overseas. A 61-year-old woman was admitted to our hospital and diagnosed with ascending colon cancer and simultaneous multiple lung metastases. The patient underwent a right hemicolectomy and was treated with CPT-11 (150 mg/m(2)) on day 1 and oral UFT and oral LV on days 1-14. This treatment cycle was repeated every 3 weeks. A CT examination after 4 cycles of chemotherapy revealed a partial response of multiple lung metastases, and the next examination after 6 cycles revealed a complete response. The adverse effects observed during this chemotherapy regimen were leucopenia (grade 1), neutropenia (grade 2), vomiting (grade 2) and hair loss (grade 1). The patient is now receiving her 22nd cycle of chemotherapy, and her multiple metastases have shown a complete response for one year. The CPT-11 and UFT/LV combination therapy was well tolerated and was covered by the national health insurance system in Japan. This treatment may enable prolonged survival and improve quality of life in patients with metastatic colorectal cancer.

Amebic liver abscess rupturing into the lesser omentum space.

A case of an amebic abscess localized in the lesser omentum is reported. There was no sign of a liver abscess in the imaging examination or the operative findings. However, it is likely that the amebic infection occurred after a liver abscess ruptured into the abdominal cavity. Early diagnosis and therapy are required when an abscess of unknown origin borders the liver, given the possibility of amebic abscess.

Whole body MRI for detecting metastatic bone tumor: comparison with bone scintigrams.

PURPOSE: To compare the effectiveness of whole body MRI (WB-MRI [magnetic resonance imaging]) and bone scintigram (BS) at detecting bone metastasis. MATERIALS AND METHODS: WB-MRI was performed on 16 patients for detecting bone metastasis (6 breast carcinoma, 7 prostatic carcinoma, 1 renal cell carcinoma [RCC], 1 hepatocellular carcinoma [HCC], and 1 primary unknown). BS was also performed in all cases. Patients were placed on a table top extender (Philips Medical Systems). The maximal longitudinal field of view (FOV) was 200 cm. At first, the total spine was imaged in the sagittal plane with a three-station approach for two image sets (fast spin-echo [SE] T1-weighted images [T1WI] and short tau inversion recovery [STIR] images). The whole body was then imaged in the coronal plane with a seven-station approach for two image sets (fast field echo [FFE] T1WI and STIR). Total examination time, including patient positioning, was within 40 min. Three independent radiologists interpreted the imaging data. RESULTS: WB-MRI identified 5 cases of 24 lesions as bone metastasis, while BS identified 3 cases of 25 lesions. Concordance between WB-MRI and BS was seen in 3 cases of 22 lesions (81%). For two cases of 2 lesions, which were identified only with WB-MRI, the lesions were located in the sacrum and thoracic spine. For one case of 3 lesions, which was identified only with BS, the lesions were located in the skull and rib. CONCLUSION: WB-MRI was an excellent method for screening bone metastasis, especially the vertebral body.

[A case of multiple superficial esophageal cancers with liver cirrhosis successfully treated by radiotherapy].

We report a case of multiple superficial esophageal cancers with liver cirrhosis successfully treated by radiotherapy. The patient was a 55-year-old man with liver cirrhosis who was under the treatment of internists at our hospital. Upper digestive tract endoscopic examination revealed multiple superficial esophageal cancers. We performed radiotherapy because pancytopenia was found in his peripheral blood data. The treatment was started on a outpatient basis, but the patient was hospitalized after sixteen treatments were finished because of hematemesis. Total irradiation was 66 Gy, and complete reduction was obtained. Eight months after the treatment, the patient shows no signs of recurrence. These results suggest that radiotherapy is an effective treatment for multiple superficial esophageal cancer.

[A case of resected spinal metastasis following colectomy and hepatectomy for descending colon carcinoma].

The patient was a 49-year-old man. In 1995, he underwent left hemicolectomy for descending colon carcinoma, and in 1996, partial hepatic resection was performed for liver metastasis. Post-operative chemotherapy was performed with 5'-DFUR. Five years later, he had lumbar and femoral pain. X-ray and MRI examination revealed a compression fracture and a spinal tumor at the XII thoracic vertebra. Though chemoradiotherapy was performed, the symptoms of pain, numbness and muscle weakness progressed. A resection of the metastatic spinal tumor was performed. Following several systemic chemotherapies, such as 5-FU/l-LV, CPT-11 + 5-FU/l-LV and low-dose CPT-11/UFT, radiotherapy was performed for the progressed bone tumor. At 2 years after surgery, he is still able to walk and no other site of recurrence has been detected.

[Pancytopenia and ARDS with high dose hepatic arterial infusion].

The patient was a 74-year-old woman with gastric cancer with multiple liver metastasis. She was treated with daily oral administration of TS-1 100 mg/day (day 1-21) and systemic administration of CDDP 90 mg (day 8) as neoadjuvant chemotherapy for 2 courses. As metastatic lesions became smaller, we performed distal gastrectomy. TS-1 was started for the residual cancer lesion. However, liver metastatic lesions increased in size, so we carried out intraarterial chemotherapy (IAC), Nausea appeared at 9 days, pancytopenia at 28 days and ARDS at 78 days after IAC. She died due to ARDS.

[A case of esophageal cancer successfully treated by chemoradiotherapy after resection for multiple liver metastasis of sigmoid colon cancer].

The patient was a 56-year-old man. Colonoscopic findings showed a cancerous lesion of the sigmoid colon and we performed curative sigmoidectomy. Four months after the operation, abdominal CT scan revealed multiple metastatic lesions in the liver. We performed lateral segmentectomy and partial resection of the S4, S6, S8 segments and cannulation for hepatic arterial infusion chemotherapy. Continuous hepatic arterial infusion chemotherapy with 5-FU (1,000 mg/body/day) was performed for two weeks as a postoperative adjuvant chemotherapy. Immediately after the therapy, endoscopic examination for upper digestive tract showed a 0-lpl type cancer lesion in the middle of the thoracic esophagus. Concurrent chemoradiotherapy with low-dose FP was efficacious and a complete response was obtained. The patient has survived for nine months after the operation without any sign of recurrence. It is suggested that concurrent chemoradiotherapy an effective treatment for esophageal cancer.

[A case of metastatic vaginal tumor of rectal cancer].

The majority of vaginal metastases from extra-genital tumors are from colorectal cancer. A case of metastases to the vagina from a huge rectal carcinoma is described. A 55-year-old woman was admitted to the hospital because of a barium ileus after upper GI. Further examination revealed that she had a huge rectal carcinoma. Hartmann's operation combined with resection of the right ureter, posterior wall of the uterus and left ovary was performed. Postoperative chemoradiotherapy was performed with 60 Gy of irradiation to the small pelvis with 500 mg/day continuous infusion of 5-FU. After 18 months, she had genital bleeding. Digital examination revealed a vaginal tumor and metastasis of the rectal carcinoma to the vagina was confirmed histologically. Abdominoperineal resection of the rectum and vagina combined with simple total hysterectomy and bilateral salpingo-oophorectomy was performed. Thirty-three months after operation, there is no sign of recurrence.

[TS-1/CDDP therapy for advanced gastric cancer as neoadjuvant chemotherapy].

Five patients with inoperable advanced gastric cancer were treated with combination chemotherapy of TS-1 and cisplatin (CDDP). TS-1 of 80-120 mg/body/day was orally administered for 3 weeks followed by 2 drug-free weeks, and 60 mg/m2/day of CDDP was venally administered on Day 8. It was possible to evaluate all 5 patients for response and toxicity. Only low grade toxicities (Grade 1 or 2) of leukocytopenia, neutrocytopenia, anemia, nausea, diarrhea and stomatitis were seen. Four of 5 patients achieved a partial response, for a response rate of 80.0%. Stomach, liver, lymph node and peritoneal tumors responded to TS-1/CDDP. TS-1/CDDP therapy produces a high response in cases of gastric cancer, and it is useful as a neoadjuvant chemotherapy.
