Case Reports[Combination Therapy of Oxycodone and Tapentadol Was Effective for Intractable Pain Caused by Breast Cancer Bone Metastasis - A Case Report].
A 52-year-old woman had been prescribed oral medication of acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and oxycodone for intractable pain associated with thoracic metastasis of breast cancer. However, the pain control was poor. ⋯ No side effects from the combined opioids were observed. This finding indicates the potential of administrating a combination therapy of m-opioid receptor agonists(such as morphine, oxycodone, and fentanyl)with tapentadol, which has a noradrenaline reincorporation-inhibiting action, as an effective remedy for alleviating intractable pain complicated with neuropathic pain.

[Treatment of Regorafenib in Patients with Metastatic or Unresectable Gastrointestinal Stromal Tumor after Failure of Imatinib and Sunitinib].
Imatinibmesylate has dramatically improved the survival with unresectable or metastatic GIST, whereas many patients subsequently develop imatinib resistance. Followed by sunitinib, regorafenib has been approved since 2013 in Japan. We aimed to assess efficacy and safety of regorafenibin GIST patients in clinical setting. ⋯ The most common Grade 3 toxicity was hand-and-foot skin reactions(4 of 11; 36.4%), followed by hypertension(3 of 11; 27.3%). Dose reduction was required in 8 patients. Although dose modifications due to toxicities were very common, some patients achieved long PFS with regorafenibtreatment.

Case Reports[Clinical Efficacy of Paclitaxel plus Bevacizumab Combination Therapy for Bone Marrow Carcinomatosis Arising from Breast Cancer - A Case Report].
We report a case of a 42-year-old woman with bone marrow carcinomatosis in the course of metastatic breast cancer who responded well to paclitaxel plus bevacizumab(PTX plus Bev)combination therapy. Four years after initial breast conserving surgery, she was admitted to our hospital with back pain and general malaise and was diagnosed as multiple bone metastases with bone marrow carcinomatosis originating from previous breast cancer(ER+/HER2-). ⋯ There has been no sign of progression at 1 year after beginning the treatment. Therefore, we conclude that PTX plus Bev combination therapy could be effective and sustainable treatment for bone marrow carcinomatosis arising from metastatic breast cancer.

It has been reported that favorable influences of cytotoxic agents to anti-tumor immune response included immunogenic cell death and suppression of regulatory T cell and myeloid-derived suppressor cell. Some clinical trials showed that the addition of immune checkpoint inhibitor to standard chemotherapy improved efficacy in patients with non-small-cell lung cancer or malignant melanoma in first-line settings. Phase III trials of the combination of immune checkpoint inhibitor and chemotherapy in several malignancies are ongoing.

[A Retrospective Analysis of Systematic Lymphadenectomy for Loco-Regional(pT1)Epithelial Ovarian Cancer].
The incidence of lymph node metastasis in pT1 epithelial ovarian cancer is between 5% and 21%. Most cases with lymph node metastasis are those of serous carcinoma; it is relatively rare in mucinous carcinoma. Therefore, there is a recent trend to omit systematic lymphadenectomy in early stage mucinous carcinoma. The purpose of this study was to verify whether the omission of systematic lymphadenectomy in mucinous carcinoma is oncologically safe. ⋯ According to our study, lymph node metastasis in pT1 mucinous carcinoma has a rate of 22.2% and some affected cases were not detected by presurgery imaging studies. Therefore, we need to be careful about the omission of systematic lymphadenectomy in mucinous carcinoma.
