In September 2023, the Japan Society of Pain Clinicians (JSPC) issued this consensus statement on chronic pain treatment in cancer survivors. With recent advances in the early diagnosis and treatment of cancer, its prognosis has improved, so prolonged pain in cancer survivors is considered to represent chronic pain and should be addressed. In this statement, we emphasize that not all cancer survivor pain is cancer pain.

Due to its low prevalence, little is known about efficacious systemic chemotherapies in cases where the tumors are unresectable or metastatic. In addition, the location of the disease can contribute to poor survival regardless of the response to therapy, as the tumor's position can cause pulmonary artery hypertension either rapidly or chronically.

However, an initial clinical presentation of bone metastasis in gastric cancer patients is relatively rare. The current study presents two cases of gastric cancer diffusely metastasized to the spinal vertebrae and with a single metastasis to the trapezium, respectively.

Two molecular targeted agents, everolimus and sunitinib, have recently been shown to provide an additional treatment benefit for pulmonary neuroendocrine tumors. However, little information is available regarding the usefulness of streptozocin chemotherapy.

The patient had undergone surgical resection three times for relapsed vulvar EMPD over a period of 12 years, but developed locally advanced and unresectable EMPD. As pathological examination indicated that the lesion was positive for human epidermal growth factor receptor 2 (HER2) on immunohistochemical staining, the patient was treated with trastuzumab plus paclitaxel.

The patient's disease relapsed, involving the pancreas, and was diagnosed as inoperable IMT 13 months after the cholecystectomy. The patient failed to respond to steroid and non-steroidal anti-inflammatory drug therapy, but subsequently exhibited a good response to vinorelbine and methotrexate combination chemotherapy.

Sporadic intrathoracic MPNST is difficult to diagnose and treat. Because of the rarity of intrathoracic MPNST, the optimal method of diagnosis and the efficacy of chemotherapy are unknown.

However, the LC levels in end-stage cancer patients treated only with palliative care remained unclear. The present study was performed to examine the plasma LC levels of terminally ill and hospitalized patients.

The present study was designed to assess the usefulness of early FDG-PET examination for predicting subsequent tumor size reduction in response to molecular targeted agents in metastatic non-small cell lung cancer (NSCLC) with sensitive gene anomalies.

However, the underlying cofactors affecting the increased urinary excretion remain unclear. The present study was performed to evaluate the dynamics of LC in plasma and urine after CDDP chemotherapy and to examine the relations with clinical parameters, such as gender, body mass index (BMI), and renal function.

Molecular targeted agents generally have little contribution to alopecia. We encountered a case of alopecia that developed gradually over 2 months after initiation of alectinib administration for the treatment of ALK-positive NSCLC.

In Japan, the aging of the society will be more ac- celerated in future, and our medical system for the home care and the out-of-hospital terminal care will be revised. Therefore it is necessary for the university hospitals to lead the preparation of the palliative care as a part of the community combined care system.

CPB may allow for a reduction in opioid dosage, and may alleviate some of the unwanted side effects of these drugs. However, there is a substantial risk of withdrawal symptoms after reduction of opioid dose.

In performing FOLFOX (infusional 5-FU/LV with oxaliplatin) for advanced colorectal cancer, neurotoxicity of oxaliplatin (L-OHP) is the serious dose limiting factor. On the other hand, goshajinkigan is recently considered as an effective agent for the neurotoxicity of taxanes in Japan. We have applied goshajinkigan (TJ 107) for a case of advanced colon cancer with mFOLFOX 6, and experienced a reduction in numbness, the adverse effect of LOHP.

Previously, PPN stimulation was reported to induce prolonged responses (PRs) in intracellularly recorded caudal pontine neurons in vitro. The present study used intracellular recordings in semihorizontal slices from rat brain stem (postnatal days 12-21) to determine responses in MED neurons following PPN stimulation.

We investigated the antinociceptive interaction between endomorphin-1 and nifedipine, an L-type calcium channel blocker, microinjected into the midbrain ventrolateral periaqueductal gray (vPAG), using the spinally-organized tail-flick test and the supraspinally-organized tail-pressure test in rats. Sprague-Dawley rats were stereotaxically implanted with a guide cannula lowered into the vPAG.

Formalin injection into the hindpaw of the rat induces the nocifensive flinching behavior and the expression of Fos-like immunoreactivity (Fos-LI) in the spinal cord. Sevoflurane significantly suppressed the flinching behavior and decreased the number of Fos-LI neurons in the dorsal horn of spinal cord compared with the control group.
