A 46-year-old woman presented with discomfort in her right lateral gaze, right-sided headache, and facial numbness 17 days after concurrent chemoradiotherapy(CCRT)for a Stage ⅢB cervical cancer. The initial imaging investigations, maxillofacial and otolaryngology reviews did not reveal a diagnosis. After 54 days of CCRT, her symptoms deteriorated. Magnetic resonance imaging(MRI)showed a tumor in the right infratemporal fossa and its biopsy confirmed a metastatic cervical cancer. In view of the rapid deterioration and the potential visual loss, palliative intensity-modulated radiotherapy(IMRT) was given. Although the symptoms improved temporarily, multiple metastases were subsequently found. Despite chemotherapy, the patient died 11 months after developing the symptoms of infratemporal fossa metastasis.

Ovarian clear cell carcinoma(OCCC)shows a poor response to standard chemotherapy, and it is often difficult to choose a regimen for patients with recurrent OCCC. Several reports have suggested a synergistic effect between gemcitabine and cisplatin; another report suggested that gemcitabine, platinum, and bevacizumab are efficacious against recurrent ovarian cancer. We treated patients with OCCC using a combination chemotherapy regimen consisting of gemcitabine(1,000 mg/ m2)and cisplatin(40 mg/m2)on days 1 and 15, and bevacizumab(15 mg/kg)on day 1, with the cycle repeated every 4 weeks. Six patients received this therapy after informed consent, and 2 evaluable patients showed a partial response. Adverse events were mild, with Grade 3 anemia, leukopenia, and neutropenia occurring in 67%, 33%, and 17% of cases, respectively. No Grade 4 events were observed, including hematological or non-hematological toxicities. This suggests that a regimen of combined gemcitabine, platinum, and bevacizumab can be efficacious and feasible for the treatment of OCCC.

We reviewed our clinical experience of olaparib treatment for patients with platinum-sensitive recurrent ovarian, fallopian tube, and peritoneal cancer. Of the 10 cases, the primary sites of cancer were the ovaries, fallopian tubes, and peritoneum in 7, 1 and 2 cases, respectively. The median period of treatment administration was 10 months. The observed Grade 3 or 4 adverse events as per the Common Terminology Criteria for Adverse Events version 4.0 were: anemia, leukopenia and neut r openia in 4, 4 and 3 cases, respectively. Eight cases needed treatment to be interrupted, and 5 cases required a reduction in dose. Three patients were treated for more than 12 months, while the others had to discontinue due to disease progression. However, none of the patients had to discontinue treatment due to adverse events. Therefore, it appears that olaparib can be safely used despite some patients requiring a withdrawal or reduction in treatment.

We report a rare case of liver recurrence of gastric cancer 14 years and 3 months after curative gastrectomy. An 81-yearold man underwent total gastrectomy, D2 lymphadenectomy, Roux-en-Y reconstruction, and cholecystectomy for advanced gastric cancer in November 2002. H e was diagnosed pathologically with M, Type 5, 53×42 mm, tub2>tub1, pT4a, ly2, v2, pN1, pPM0, pDM0, M0, pStage ⅢA(JGCA 15th). Postoperative adjuvant therapy was not administered. He was followed up for 5 years after surgery without adjuvant therapy, and he did not exhibit recurrence. In February 2017, he experienced difficulties in swallowing and visited our hospital. Abdominal contrast-enhanced CT showed an 8×5 cm liver tumor in the lateral segment. Part of the tumor protruded to outside of the liver, and the tumor invaded and pushed the jejunum in the Roux limb. We performed liver biopsy and diagnosed him with liver metastasis of recurrent gastric cancer. Late relapse after gastrectomy, especially after 10 years or more, is very rare.

We encountered a case of uterine leiomyosarcoma with multiple lung metastases. The patient was a 52-year-old woman who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by chemotherapy with gemcitabine and docetaxel. After 1 cycle of chemotherapy, the lung metastasis was reduced, but at the same time, she developed bilateral pneumothorax. Chemical pleurodesis using talc was performed. The lungs were expanded and stabilized in 7 days. After 5 cycles of chemotherapy were administered, no recurrence of pneumothorax and adverse effects were observed.

A 53-year-old patient with recurrent ovarian clear cell adenocarcinoma developed fever (39°C) and cough on day 28 of liposomal doxorubicin chemotherapy, the 4th cycle of the 4th regimen since initial treatment. Drug-induced interstitial pneumonia was suspected from a chest CT image showing diffuse ground-glass opacities; however, we deduced pneumocystis pneumonia from the elevated serum beta-D-glucan levels. After effective treatment with sulfamethoxazole and amphotericin B, the patient's symptoms and radiological findings improved. Pneumocystis pneumonia is an opportunistic infection that poses a risk not only for patients undergoing aggressive immunosuppressive therapy, those infected with HIV, and those with transplants, but also for patients undergoing chemotherapy. When pneumonia is diagnosed during chemotherapy, it is essential to consider the possibility of pneumocystis pneumonia.
