Cytomegalovirus(CMV)infection is a well-recognized complication of immunodeficiency. We present the case of a 90- year-old female admitted due to gastric cancer. Fifty-seven days after gastrectomy, intestinal juice was observed from the umbilical wound, which was suspected of anastomotic failure or gastrointestinal perforation. selleck compound Abdominal computed tomography didn't reveal gastrointestinal perforation. CMV enteritis was diagnosed by transanal double-balloon endoscopy from the cecum to the oral side 15 cm of the ileum. Enterocutaneous fistula was considered to be caused by CMV enteritis. The intestinal fluid outflow from the wound disappeared treated with ganciclovir, and the ulcer in the intestinal tract disappeared, too. We report this case to reinforce the importance of considering CMV infection as a differential diagnosis in gastrointestinal perforation of compromised patients.Recent improvements in the survival of patients after esophagectomy have led to an increase in the occurrence of gastric tube cancers(GTC). We retrospectively examined 7 patients who were surgically treated for GTC among 13 patients who were diagnosed between April 2004 and December 2018. Partial gastrectomy with regional lymph node dissection was performed in 6 patients while total resection of the stomach was performed only in 1 patient. Postoperative complications included 1 anastomotic leakage and 1 subcutaneous abscess. We performed subtotal gastrectomy with preservation of the upper region of the gastric tube in 3 patients. In these patients, blood flow was confirmed from the remnant esophagus to the upper region of the gastric tube using indocyanine green fluorescence imaging. The pathological stage of the treated GTCs were 4 cases of Stage ⅠA, 2 of Stage ⅠB, and 1 of Stage ⅡA. Median follow-up time and postoperative survival time were 32 months and 46.5 months, respectively. Most of our surgically treated cases were early gastric carcinomas that could be radically resected.Case 1 A 51-year-old man with advanced gastric cancer and peritoneal metastasis was referred to our hospital. He received fourth-line chemotherapy with nivolumab, but it became PD. Next, he received S-1 plus docetaxel therapy as fifth- line therapy. After 2 courses of S-1 plus docetaxel, erythema and blisters appeared on his limbs, with erosions of the oral mucosa and penis. We diagnosed Stevens-Johnson syndrome(SJS)based on the clinical and pathological findings. He received steroid treatment, but the cutaneous symptoms persisted; therefore, it was impossible to continue the chemotherapy because of the SJS. Case 2 A 75-year-old woman with recurrence of peritoneally disseminated gastric cancer received third-line chemotherapy with nivolumab. After 1 course of nivolumab, erythema appeared on her body and limbs, with erosion of the lips and oral mucosa. We diagnosed SJS based on the clinical findings. She received steroid treatment, but the cutaneous symptoms persisted; therefore, it was impossible to continue chemotherapy because of the SJS. It should be noted that the onset of serious irAEs, such as SJS, might make continuous chemotherapy difficult.We report a case of recurrent hepatocellular carcinoma(HCC)successfully treated by radiation therapy. A 79-year-old woman was diagnosed with HCC and underwent liver resection. Seven months after resection, CT and MRI detected a new HCC, and she had a surgery again. One year after the surgery, CT and MRI detected local recurrence, and she underwent the third operation. Three months after the operation, the third liver recurrence was treated by transcatheter arterial chemoembolization( TACE). Four months later, a new lesion was detected and treated by stereotactic body radiation therapy(SBRT) twice. She remains alive without recurrence 27 months after the last radiation therapy. Very few evidence is reported of radiation therapy for HCC, but this case suggests that radiation therapy provides a benefit for patients with HCC after other treatments.An 82-year-old woman who underwent total thyroidectomy and left cervical lymph node dissection 21 years ago admitted our hospital because of left cervical pain. Neck CT scan showed a 6 cm tumor on the left clavicle. Pathological diagnosis by needle biopsy revealed poorly differentiated to undifferentiated carcinoma, positive for TTF-1, and diagnosed as thyroid cancer lymph node metastasis anaplastic transformation. Administration of lenvatinib was started after radiation therapy. Since thrombocytopenia was observed, lenvatinib was gradually reduced from 14 mg and the dose was continued at 4 mg. The tumor shrinked and the effect of chemotherapy was partial response. She survived for 3 years while continuing lenvatinib. We reported long-term survival due to radiation therapy and lenvatinib of anaplastic transformation of thyroid cancer in lymph node metastasis due to radiation therapy and lenvatinib.We present a case of locally advanced rectal cancer(LARC)treated by robot assisted intersphincteric resection(ISR)and lateral lymph node dissection(LLND)after neoadjuvant chemotherapy(NAC). The patient was a 69-year-old female with the diagnosis of adenocarcinoma of the rectum Rb. The clinical stage diagnosis was cT3N0M0, cStage Ⅱ. NAC with FOLFOXIRI(5-fluorouracil/oxaliplatin/leucovorin/irinotecan)plus bevacizumab(BEV)was inisiated as NAC. Tumor volume reduction of primary lesion was evaluated by CT scan and colonoscopy after 6 courses of FOLFOXIRI plus BEV including omit of BEV on last course and were judged as partial response(PR)and no distant metastasis. With maintenance of tolerability for surgery even after NAC, robot assisted ISR and LLND were safely performed with curative resection. The histopathological treatment effect of post NAC was diagnosed as Grade 1b and the final pathological stage was ypT3pN0cM0, ypStage ⅡA. We experienced a case of LARC was performed FOLFOXIRI plus BEV as NAC followed by robotic ISR and LLND with anal preservation.The case is a 17-year-old man. He had complained of right lower abdominal pain for a week. He had no symptoms such as fever, weight loss, or night sweats. He was diagnosed with intussusception by abdominal contrast-enhanced CT and was hospitalized. The day after hospitalization, lower gastrointestinal endoscopy was performed, and a tumor 25 mm in size was found in the invagination of the ileum. Intussusception was recovered by intestinal scope insufflation, and the tumor was found to be a type 1 tumor located approximately 5 cm proximal to the Bauhin's valve. On day 17 of hospitalization, he had intussusception again at the time of surgery, and performed laparoscopic reduction before performing laparoscopy-assisted partial resection of the small intestine and appendectomy. The postoperative course was good and he was discharged on POD12(on day 29 of hospitalization). Histopathological diagnosis was diffuse large B-cell lymphoma(DLBCL), and chemotherapy was to be administered at the referral hospital. In intussusception of the adolescents and young adults(AYA)generation, such as this case outside of childhood, it is necessary to treat the patient with consideration for the presence of neoplastic lesions such as malignant lymphoma.
