We report our experience with a case of iatrogenic immunodeficiency-associated lymphoproliferative disease in a patient who had been treated with methotrexate (MTX) for rheumatoid arthritis for 9 consecutive years, which showed natural remission after discontinuation of the MTX therapy. The patient was a 64-year-old woman who was admitted emergently to our hospital with hematemesis and melena. She presented with multiple gastric ulcers and bilateral tonsillitis with a central ulcer. Biopsy of these lesions raised the suspicion of diffuse large B-cell lymphoma. Positron emission tomography (PET)- computed tomography( CT) showed increased fluorodeoxyglucose( FDG) accumulation in the pharynx, cervical lymph nodes, liver, spleen, stomach, distal part of the ileum, and para-aortic lymph nodes, with a maximum standard uptake value of 26.85. Blood test showed elevated lactate dehydrogenase( LDH)( 321 U/L) and interleukin( IL)-2R( 3,531 U/mL) levels. After discontinuation of MTX, the sore throat subsided, and the tonsillitis, lymph node enlargement, and ulcers were resolved. The levels of LDH and IL-2R returned to within the normal range. The patient could be categorized into a regressive disease group with relatively favorable prognosis among patients with MTX-induced lymphoproliferative disease. However, she should continue to be followed up regularly because there remains a possibility that lymphoproliferative disease may relapse after the discontinuation of MTX. Source

A 75-year-old woman with a chief complain of anal pain visited the emergency department. She was diagnosed as having S-colon cancer perforation accompanied by an intra-abdominal abscess. Computed tomography (CT)-guided drainage was applied to the intra-abdominal abscess. Six days after drainage, the patient's condition progressed to acute respiratory failure due to heart failure, and ventilator support was provided temporarily. The patient's cardiopulmonary function improved with conservative management. S-colon cancer was detected during colonoscopy examination, and biopsy indicated a tub2 tumor. Next, S-colon resection with D3 lymph node dissection was performed. The postoperative course was uncomplicated. Two months after surgery, liver metastases were detected on CT. Since the patient's performance status (PS) was 3, it was impossible for her to undergo chemotherapy. Four months after surgery, her PS was restored to 2 and the liver metastases were exacerbated, as seen on CT. The patient began chemotherapy (XELOX plus bevacizumab, 30% reduced dose). Eight months after the start of chemotherapy, 9 courses had been administered, the carcinoembryonic antigen (CEA)/carbohydrate antigen (CA) 19-9 level had decreased to the reference value, and the decrease in size of the liver metastases indicated a partial response (PR), as assessed by CT.

We report a case of a 64-year-old man with multiple lung metastases after gastric cancer surgery. This patient was initially treated with S-1. However, he experienced adverse effects, and subsequently, he was effectively treated with cisplatin (CDDP) and irinotecan (CPT-11). In July 2010, the patient experienced a decrease in appetite and underwent a detailed examination. He also underwent distal gastrectomy in the same month. The postoperative diagnosis was T4a( SE), N2, M0, Stage IIIB. In November 2010, adjuvant chemotherapy with S-1 was initiated. In February 2011, the patient developed a skin disorder( grade 3) and generalized edema along with walking difficulty, which were identified as adverse effects of S-1. Evidently, S-1 was contraindicated for this patient, and adjuvant therapy was discontinued. In September 2011, contrast -enhanced thoracoabdominal computed tomography( CT) was performed and para-aortic lymph node metastasis and multiple lung metastases were detected. CDDP+CPT-11 therapy was initiated. By June 2012, 8 courses had been administered, and the patient had a good partial response. With regard to chemotherapy for advanced or recurrent gastric cancer, there is no consensus on a treatment policy for cases in which S-1 cannot be used owing to adverse effects. CDDP+CPT-11 therapy is considered a safe and effective choice. Source

We report a case of a 55-year-old woman who underwent mastectomy and axillary lymph node dissection for right breast cancer( T2N1cM0) 7 years previously. She had been experiencing chest pain for 1 year. Ultrasonography( US) showed a low echoic mass, 1 cm in diameter, near the rib in the right breast (class 5).Magnetic resonance imaging (MRI) and positron emission tomography( PET)-computed tomography( CT) scans revealed an 8-cm wide, segmentally enhancing soft tissue lesion and enhanced lymph nodes at the right edge of the sternum. Under the diagnosis of local recurrence, the patient received chemotherapy consisting of adriamycin and cyclophosphamide( AC) and docetaxel. Definite improvement in chest wall metastasis was observed following this treatment. By changing the treatment to endocrine therapy, the disease has been effectively controlled. Source

A 68-year-old man underwent total gastrectomy for gastric cancer(Stage II). Adjuvant chemotherapy with S-1 was administered. At 21 months after the operation, he received a nephron catheter because of hydronephrosis caused by para-aortic lymph node metastases. Then, weekly paclitaxel was given as a second-line treatment. However, his tumor marker level increased and he therefore received CPT-11 (160 mg/m2) as a third-line treatment at 28 months after the operation. At 7 days after the first CPT-11 administration, he was hospitalized because of a severe adverse event involving nausea and general fatigue, which caused a continuous fever of 39°C and renal failure at 14 days after administration. However, hydration enabled him to recover several days later. Computed tomography scan revealed the lymph node metastases to be partial remission. Source
