Case Reports[A Case of Complete Response to Computed Tomography-Guided Celiac Plexus Neurolysis of Pain Associated with Postoperative Recurrence of Colon Cancer].
The patient was a man in his 40s, who had undergone laparoscopic ileocecal resection with lymph node dissection(D3)for cecal cancer in January 2012. Histopathological examination of the resected specimens had revealed StageⅡ primary tumor with subserosal invasion and positive metastasis in 1-3 regional lymph nodes(pT2[SS]n1[+]). The pathological stage was Ⅲa(fStage Ⅲa), and the tumor showed RAS gene mutation. ⋯ The patient was discharged without major complications, and the base opioid dose was gradually reduced. Since the patient did not require any rescue medication during daytime on some days, the reduction of the base opioid dose was significantly effective in improving the patient's quality of life(QOL). In patients with pain possibly caused by metastasis to the para-aortic nodes, this local therapy technique may be considered.

Case Reports[Indoleamine 2,3-Dioxygenase Activity during Long-Term Letrozole Therapy for Hormone Receptor-Positive Breast Cancer].
Endocrine therapy is effective for elderly patients who are diagnosed with estrogen receptor-positive breast cancer and cannot receive surgical treatment or chemotherapy because of advanced age. The duration of response in patients receiving letrozole is approximately 10.3 months. There are few cases with more than 3 years of response. ⋯ Trp and Kyn levels were measured using high-performance liquid chromatography(HPLC). The Trp/Kyn ratio decreased along with tumor reduction after letrozole therapy. These results suggest that measuring the Trp/Kyn ratio may be useful for evaluating immunological status during endocrine therapy in elderly patients with locally advanced breast cancer.

[Regorafenib and Trifluridine and Tipiracil Hydrochloride Can Potentially Improve the Survival Time for Patients with Advanced or Recurrent Colorectal Cancer].
Regorafenib and trifluridine and tipiracil hydrochloride(TFTD)have been recently used for the treatment of advanced or recurrent colorectal cancer during or after the third-line therapy. These drugs are expected to prolong survival. The progression- free survival period associated with each drug in clinical trials is known to be less than 2 months. ⋯ The MST with monotherapy and sequential therapy was 37 and 45 months, respectively. We currently have a patient who has not had cancer progression for 3 years and 6 months with monotherapy. Regorafenib and TFTD can potentially improve the survival time beyond our observations on monotherapy when used at the appropriate time and with a thorough understanding of their adverse effects.

[Combinatorial Use of Rapid-Onset Opioid and Short-Acting Opioid Is Effective against Breakthrough Cancer Pain].
Breakthrough cancer pain is divided into "predictable breakthrough pain" and "unpredictable breakthrough pain". Uncontrolled breakthrough pain in cancer negatively affects the quality of life of the patients. The short-acting opioid(SAO) requires considerable time to produce analgesia, and is not adequate as a rescue drug. ⋯ Therefore, ROO has not yet gained popularity. Here, we report that a combinatorial use of ROO and SAO is effective against breakthrough cancer pain, with SAO and ROO being suitable for "predictable breakthrough pain", and "unpredictable breakthrough pain", respectively. The effectiveness and safety of this combination were assessed for many patients with breakthrough cancer pain.

Case Reports[A Successful Treatment of Locally Advanced Breast Cancer with Using Mohs' Paste and Chemotherapy - A Case Report].
Foul smell and large amounts ofexudate, bleeding are the most common and serious symptoms with locally advanced breast cancer(LABC). Mohs' paste is made ofa mixture ofzinc chloride and used for treatment ofmalignant skin tumors. ⋯ Mohs' paste is useful for reducing symptoms such as foul smell and exudate, Bleeding. We report a successful case of treatment for LABC with using Mohs' paste and chemotherapy and surgery.
