RESUMEN
BACKGROUND: Intrapelvic aberrant needles are rare in clinical practice. Long-term foreign bodies in the abdominal cavity may form granulation tissue or an abscess, and may cause organ injury. Therefore, such foreign bodies need prompt removal. CASE PRESENTATION: A 26-year-old male athlete was referred to our hospital for investigation of an aberrant acupuncture needle in the gluteus. The needle was unable to be removed during acupuncture treatment, and the end broke off and remained in the gluteus. Abdominal X-ray examination showed a thin, 40-mm-long, metallic foreign body resembling an acupuncture needle. Abdominal computed tomography showed an abnormal shadow in the gluteus. However, it was unclear whether the tip of the needle reached the pelvic cavity. Thus, it was decided to surgically extract the needle via laparoscopic surgery under X-ray guidance as a safe and minimally invasive method. Although X-ray fluoroscopy confirmed that the aberrant needle was located in the gluteus, the needle could not be felt with the forceps, as the peritoneum surrounding the needle had granulomatous changes due to inflammation. Therefore, the retroperitoneum was further dissected to search for the needle. Once the needle was identified, its flexibility enabled it to be easily removed by grasping it directly with a needle holder. The length of the aberrant needle was 40 mm. The postoperative course was uneventful, and the patient was discharged from hospital on postoperative day 2. CONCLUSIONS: When a foreign body remains in the gluteus and its tip touches intrapelvic organs, such as the rectum, it is critical to determine the best approach for its safe removal. Given the anatomical location of the foreign body and the patient background, laparoscopic removal was considered the best approach in the present case.
RESUMEN
Despite recent advances in chemotherapy for gastrointestinal cancer, a crucial factor related to poor prognosis is reduced tolerance to chemotherapy induced by cancer cachexia. Fish oil (FO)-derived eicosapentaenoic acid (EPA) modulates inflammation in patients with various malignancies; however, the impact of FO-enriched nutrition as a combined modality therapy on clinical outcomes remains controversial. We systemically analysed chronological changes in biochemical and physiological status using bioelectrical impedance analysis in 128 gastrointestinal cancer patients provided with or without FO-enriched nutrition during chemotherapy. Furthermore, we evaluated the clinical significance of FO-enriched nutrition and clarified appropriate patient groups that receive prognostic benefits from FO-enriched nutrition during treatment of gastrointestinal cancer. The control group showed significant up-regulation of serum CRP) levels and no significant difference in both skeletal muscle mass and lean body mass. In contrast, the FO-enriched nutrition group showed no changes in serum CRP concentration and significantly increased skeletal muscle mass and lean body mass over time. Furthermore, high CRP levels significantly correlated with reduced tolerance to chemotherapy, and FO-enriched nutrition improved chemotherapy tolerance and prognosis, particularly in gastrointestinal cancer patients with a modified Glasgow prognostic score (mGPS) of 1 or 2. We conclude that FO-enriched nutrition may improve the prognosis of patients with cancer cachexia and systemic inflammation (i.e., those with a mGPS of 1 or 2).

Recurrence after neoadjuvant chemo-radiotherapy (CRT) followed by surgery is high in patients with esophageal cancer. No standard second line therapy is currently available for patients with recurrence. This study aimed to evaluate the expression of chemo-radiosensitive genes after neoadjuvant CRT in residual tumor cells. Thirteen patients with esophageal squamous cell carcinoma underwent 5-fluorouracil (5-FU) and cisplatin (CDDP) based CRT followed by surgery. Total RNA was successfully obtained from 6 formalin-fixed paraffin-embedded (FFPE) specimens using proteinase K digestion and phenol chloroform extraction. TS and DPD as the 5-FU pathway gene, ERCC1 as the CDDP pathway gene, and EGFR, VEGF, HIF1a as radioresistant genes were measured using real-time reverse transcription polymerase chain reaction; comparing the mRNA level of each gene in pre-CRT biopsy with that in post-CRT FFPE specimens. Five patients had less than one-third residual tumor cells in resected specimens histopathologically; eight had more than two-thirds residual tumor cells. There were significant increases in TS (p=0.02) and DPD (p=0.01) levels in residual tumor cells after CRT. Significant decreases in ERCC1 (p=0.03), EGFR (p=0.01), VEGF (p=0.003) and HIF1a (p=0.003) levels were observed. 5-FU and CDDP based CRT up-regulated 5-FU pathway genes and down-regulated CDDP pathway and radioresistant genes. The expression of chemo-radiosensitive genes was significantly changed in residual tumor cells after CRT. Gene expression analysis of residual tumor cells in FFPE specimens may be useful when selecting a second line chemotherapy regimen for recurrent esophageal cancer after CRT.

BACKGROUND AND OBJECTIVES: This study aimed to evaluate the significance of preoperative C-reactive protein (CRP) as a prognostic marker for carcinoembryonic antigen (CEA)-independent stage I or II colorectal cancer (CRC) patients. METHODS: Preoperative CRP was measured in 300 CRC patients to assess its relationships with clinicopathological factors and long-term survival. Based on the results of the initial study, the relationship between preoperative CRP and long-term survival was evaluated with reference to adjuvant 5-fluorouracil (5-FU)-based chemotherapy in a further 128 stage II patients. RESULTS: CRP was associated with disease progression and factors reflecting nutritional depletion such as serum albumin, lymphocyte count and body weight loss ratio. In stage I or II patients, CRP could predict early disease recurrence, even when a CEA test could not. Multivariate analyses revealed that CRP was an independent prognostic variable in stage I or II patients. In the additional 128 stage II patients, CRP-positive patients showed a 3-year survival rate of only 55% without adjuvant chemotherapy, but this increased to 90% with adjuvant chemotherapy. CONCLUSIONS: CRP may be a potent prognostic and therapeutic indicator that provides valuable information for determining the need for adjuvant chemotherapy in stage II CRC patients.
