A 49-year-old woman was referred to our hospital with a history of upper abdominal pain for two weeks and was diagnosed with synchronous cancer. During hospitalization, the patient underwent laparoscopic distal gastrectomy + resection of bilateral ovaries + partial resection of both small intestine and descending colon. Pathological examination revealed a synchronous cancer consisting of early gastric cancer with poorly differentiated adenocarcinoma located in mucosa, with lymph node metastasis (3+/29) (T1N1M0, stage IB); and diffuse large B cell lymphoma of small intestine involving descending colon and bilateral ovaries, with lymph node metastasis (2+/5) (Ann Arbor IIE). The patient recovered well, without any obvious complications and was discharged on post-operative day 7. The patient received six cycles of chemotherapy after operation. She has been doing well with no evidence of recurrence for 13 mo.展开更多

Propensity score matching was carried out based on age, gender, pathological staging of the disease and administration of neoadjuvant chemoradiation. Data regarding preoperative staging, surgical technique, pathologicalresults, postoperative recovery and complications were reviewed and compared between the LAPR and OAPR groups. Perineal closure around the stoma and pelvic floor reconstruction were performed only in OAPR, not in LAPR. Therefore, abdominoperineal resection procedure-specific surgical complications including parastomal hernia and perineal wound complications were compared between the open and laparoscopic procedure. Regular surveillance of the two cohorts was carried out to gather prognostic data. Diseasefree survival was analyzed using Kaplan-Meier estimate and log-rank test. Subgroup analysis was performed in patients with locally advanced disease treated with preoperative chemoradiation followed by surgical resection. RESULTS: No significant difference was found between the LAPR group and the OAPR group in terms of clinicopathological features. The operation time(180.8 ± 47.8 min vs 172.1 ± 49.2 min, P = 0.190), operative blood loss(93.9 ± 60.0 m L vs 88.4 ± 55.2 m L, P = 0.494), total number of retrieved lymph nodes(12.9 ± 6.9 vs 12.9 ± 5.4, P = 0.974), surgical complications(12.3% vs 15.1%, P = 0.549) and pathological characteristics were comparable between the LAPR and OAPR group, respectively. Compared with OAPR patients, LAPR patients showed significantly shorter postoperative analgesia(2.4 ± 0.7 d vs 2.7 ± 0.6 d, P < 0.001), earlier first flatus(57.3 ± 7.9 h vs 63.5 ± 9.2 h, P < 0.001), shorter urinary drainage time(6.5 ± 3.4 d vs 7.8 ± 1.3 d, P < 0.001), and shorter postoperative admission(11.2 ± 4.7 d vs 12.6 ± 4.0 d, P = 0.014). With regard to APR-specific complications(perineal wound complications and parastomal hernia), there were no significant differences between the two groups. Similar results were found in the 26 pairs of patients administered neoadjuvant chemoradiation in subgroup analysis. During the follow-up period, no port site recurrences were observed. CONCLUSION: Laparoscopic abdominoperineal resection for multidisciplinary management of rectal cancer is safe, and is associated with earlier recovery and shorter admission time in combination with neoadjuvant chemoradiation.展开更多

Both cases had para-aortic lymph node metastasis at the time of initial surgery and received adjuvant chemotherapy for 4 years in case 1 and 18 mo in case 2. The time to recurrence was more than 8 years in both cases. After resection of the recurrent tumor, the patient is doing well with no recurrence for 6 years in case 1 and 4 mo in case 2. Patients should be followed up after colon cancer surgery considering the possibility of solitary mediastinal lymph node recurrence if they had para-aortic node metastasis at the time of initial surgery.展开更多

文摘The effect of chemotherapy on peritoneal carcinomatosis(PC) of gastric cancer remains unclear.Recently,the intraperitoneal(IP) administration of taxanes [e.g.,paclitaxel(PTX) and docetaxel(DOC)] during the perioperative period has shown promising results.Herein,we summarized the rationale and methodology for using IP chemotherapy with taxanes and reviewed the clinical results.IP administered taxanes remain in the IP space at an extremely high concentration for 48-72 h.The drug directly infiltrates peritoneal metastatic nodules from the surface and then produces antitumor effects,making it ideal for IP chemotherapy.There are two types of perioperative IP chemotherapy with taxanes: neoadjuvant intraperitoneal and systemic chemotherapy and sequential perioperative intraperitoneal chemotherapy(SPIC).In SPIC,patients receive neoadjuvant IP chemotherapy and the same regimen of IP chemotherapy after cytoreductive surgery(CRS) until disease progression.Usually,a taxane dissolved in 500-1000 m L of saline at ordinary temperature is administered through an IP access port on an outpatient basis.According to phase Ⅰ?studies,the recommended doses(RD) are as follows: IP DOC,45-60 mg/m2; IP PTX [without intravenous(IV) PTX],80 mg/m2; and IP PTX(with IV PTX),20 mg/m2.Phase Ⅱ studies have reported a median survival time of 14.4-24.6 mo with a 1-year overall survival of 67%-78%.A phase Ⅲ study comparing S-1 in combination with IP and IV PTX to S-1 with IV cisplatin started in 2011.The prognosis of patients who underwent CRS was better than that of those who did not; however,this was partly due to selection bias.Although several phase Ⅱ studies have shown promising results,a randomized controlled study is needed to validate the effectiveness of IP chemotherapy with taxanes for PC of gastric cancer.

文摘To investigate the level of telomerase activation (TA) and telomerase catalytic subunit (hEST 2) gene mRNA in patients with non small cell lung cancer, and determine whether they are associated with tumor cell apoptosis, stage, and clinical outcome Methods Primary tumor specimens from 58 patients untreated with chemotherapy and 10 cases of histologically benign and adjacent lung tissue were analyzed TA and hEST 2 were measured by means of a modified telomerase repeat amplification protocol (TRAP) assay and in situ hybridization (ISH), respectively Terminal deoxynucleotidyl transferase (TdT) mediated biotin dUTP nick end labeling (TUNEL) was used to evaluate apoptotic cells Reverse transcription polymerase chain reaction (RT PCR) was used to detect bcl 2 mRNA expression Results TA and hEST 2 were detected in 45 (77 6%) and 43 (74 1%) of 58 tumor specimens, respectively, and not detected in specimens of adjacent and benign lung tissue One case expressed hEST 2 as a weak positive Statistically significant positive association was found between the level of TA and hEST 2( r =0 85, P =0 001) TA and hEST 2 were associated with tumor stage, but not associated with tumor grade, gender and patient age Positive rate of bcl 2 mRNA was 38 (65 5%) of 58 tumor specimens The mean apoptotic index in the bcl 2 positive group (9 5±1 3) was lower than that in the bcl 2 negative one (19 8±2 1, P <0.05), suggesting that apoptotic index may be inversely associated with bcl 2 expression ( r =-0 48, P =0 041) Bcl 2 expression in the TA and hEST 2 positive group (92 1% and 89 4%) was higher than that in the negative one (50 0% and 45 0%, P =0 043 and P =0 032, respectively) The apoptotic index was lower in the TA or hEST 2 positive group (8 2±1 4, 10 7±1 1) than in the negative one (20 5±1 6, 24 2±2 1, P <0 05) A statistically significant inverse association was found between TA or hEST 2 and apoptotic index ( r =-0 45, P =0 02 and r = -0 51, P =0 001, respectively) Positive correlation was also detected between TA or hEST 2 and bcl 2 expression ( r =0 86, P =0 01 and r =0 73, P =0 024, respectively) The level of hEST 2 mRNA and apoptotic index were associated with clinical outcome in a multivariate cox regression analysis Conclusions High TA and hEST 2 were frequently detected in primary non small cell lung cancer untreated with chemotherapy, having high bcl 2 expression and a low tumor cell apoptotic rate This suggests that both TA and hEST 2 are correlated with the deregulation of apoptosis hEST 2 and apoptotic index have prognostic significance in patients with non small cell lung cancer
