ObjectiveTo explore advantages and feasibility of a new prosthesis implantation method after breast cancer surgery by reacquaint breast anatomy. MethodsThe clinicopathologic data of patients with breast cancer were retrospectively collected. The patients underwent the breast cancer surgery and prosthesis implantation with cricoid breast ligament in the Xuzhou Cancer Hospital from January 1, 2021 to May 30, 2023. ResultsA total of 10 patients were collected, with age ranging from 31 to 59 years old. Three patients received postoperative analgesia, 2 patients occurred infection, 1 patient occurred fat liquefaction. All patients did not experience capsular contracture, flap necrosis, or removal of the prosthesis. Two patients had sentinel lymph node metastasis. All patients followed-up 3 to 24 months after surgery. The BREAST-Q questionnaire was used to assess the quality of life and satisfaction after surgery, 3 patients were very satisfied, 5 were satisfied, and 2 were basically satisfied. ConclusionFrom the results of limited cases analysis in this study, it is safe and feasible to implant the prosthesis with cricoid breast ligament in selected patients after breast cancer surgery.
Objective To investigate the expression of urokinase-type plasminogen activator (uPA) mRNA in gastric cancer tissues and cancer-adjacent tissues and the relationship between its expression and biologic behavior of tumor. Methods Fourty-eight cases with gastric cancer were detected for the expression of uPA mRNA by fluorogenic probe quantitative reverse transcription polymerase chain reaction (RTPCR). Results The positive expression rate of uPA mRNA was 83.3%, 25.0%, 93.8% and 62.5% in gastric cancer tissues,cancer-adjacent tissues, gastric cancer tissues with lymph node metastasis and with non-lymph node metastasis respectively. Expression of uPA mRNA was positively related with the invasion depth of gastric cancer. Conclusion Expression of uPA mRNA is significantly increased in gastric cancer and it can be used as an indicator to judge the metastasis and prognosis of tumor.
【Abstract】ObjectiveTo study the effect of preoperative gastric arterial chemoembolization on apoptosis of lymph node metastasis of gastric cancer. MethodsForty patients with gastric cancer and lymph node metastasis underwent curative resection, among which there were 20 patients who received the preoperative gastric arterial chemoembolization, and they constituted the treatment group. The rest of the patients were included in the control group. The expressions of p53, CD95 and bcl-2 were examined by immunohistochemistry and apoptosis in the lymph node metastasis was examined by in situ terminal transferasemediated dUTP nick end labeling （TUNEL）. ResultsThe expression intensity of p53 and CD95 in lymph node metastasis of treatment group increased more significantly than that of control group, whereas the expression intensity of bcl-2 decreased in treatment group. There was a significantly positive correlation between the expressions of p53 and CD95 and the apoptosis.ConclusionPreoperative gastric arterial chemoembolization may affect the expressions of p53, CD95 and bcl-2 and may induce the apoptosis of lymph node metastasis. It may be helpful to improve the effect of curative resection of gastric cancer.
ObjectiveTo summarize research progress of quality of life in patients after colorectal cancer surgery.MethodsThe literatures about quality of life of patients with colorectal cancer surgery in recent years are reviewed.ResultsQuality of life had became an important criterion for evaluating the therapeutic effect and prognosis of cancer. At present, the assessment tools for the quality of life of colorectal cancer patients mainly included the universal scale [such as Short Form Health Survey (SF-36)], the applicable scales for cancer patients [such as European Organization for Research and Treatment of Cancer: quality of life questionaire-C30 (EORTC QLQ-C30) and European Organization for Research and Treatment of Cancer: quality of life questionaire-CR38 (EORTC QLQ-CR38)], and the special scales for stoma patients represented by City of Hope Quality of Life-Ostomy Questionnaire (COH-QOL-OQ), Stoma Quality Of Life (Stoma-QOL), Stoma Quality Of Life Scale (SQOLS), and so on. The short-term quality of life of colorectal cancer patients was lower at 1 month after operation and recovered at 3 months after operation. Five years after surgery, attention should also be paid to the long-term quality of life. Besides, postoperative quality of life of colorectal cancer patients was affected by age, occupational status, economy, preoperative physical activity level, psychological and social factor, personality, surgical method, co-morbidity, complication, stoma, and so on.ConclusionsUnderstand the longitudinal changes and influencing factors of patients’ quality of life after operation, grasp the time point of effective intervention, and select appropriate assessment tools are necessary for medical staff. It is of great significance to further optimize the clinical management pathway and improve the quality of life of patients with colorectal cancer after operation.
Through searching and evaluating the evidence on advanced prostate cancer, we found that different types of androgen deprivation had similar effect, and immediate androgen deprivation had survival benefit. For the patient with hormone-refractory prostate cancer, therapies including mitoxantrone, prednisone, docetaxel and surmine were more effective. Strontium-89 provided more effective pain relief than external beam radiation. And bisphophonate had no effect. Antiandrogen withdrawal suggested prostate specific antigen would decline, but the clinical outcome wasn’t reported.
ObjectiveTo investigate the value of different minimally invasive surgical techniques, stent placement, laparoscopic surgery, and sustained-releasing 5-fluorouracil, in solving intestinal obstruction due to colorectal cancer. MethodsFrom May 2000 to May 2010, total 68 patients with obstructed colorectal cancers in three centers were treated in two ways in terms of the stage: The first, patients with resectable tumors underwent colorectal stent placement as a ‘bridge to surgery’ guided by enteroscope under X-ray. After clinical decompression and bowel preparation, laparoscopic radical resection was performed. The second, patients with unresectable tumors underwent rectal stent placement just for palliation. Sustained-releasing 5-fluorouracil was implanted into the local cancerous intestinal tract through stent walls. ResultsFifty-one of 52 patients underwent laparoscopic radical resection successfully following stent placement, while one failed and died during follow-up 93 d postoperatively. Forty patients with successful laparoscopic surgery were followed up in 3 to 36 months (with an average of 15 months) without tumor planting in the incision, postoperative local recurrence or anastomotic stricture. Fifteen unresectable patients and one high-risk, intolerable patient underwent rectal stent placement and implantation of sustained-releasing 5fluorouracil. During follow-up 3 to 24 months (with an average of 14 months), 11 died, who survived for (350±222) d (range 101-720 d), and 5 were still alive for 3 to 13 months (with an average of 9 months) without intestinal obstruction. ConclusionsLaparoscopic surgery combined with stent placement is an effective and safe procedure for resectable obstructed colorectal cancer. For unresectal obstructed rectal cancer, rectal stent placement combined with sustained-releasing 5-fluorouracil can prolong survival time avoiding colostomy.
ObjectiveTo evaluate the role of surgical resection on synchronous multiple pulmonary nodules identified difficultly in clinics.MethodsThe clinical data of 97 patients with synchronous multiple pulmonary nodules who received surgical resection between 2012 and 2019 in Hunan Cancer Hospital were retrospectively analyzed. There were 72 males and 25 females, aged 58.1±9.0 years. Among these patients, there were 78 patients with ipsilateral and 19 patients with bilateral pulmonary nodules. Clinicopathological parameters between main nodules and secondary nodules were evaluated. Perioperative morbidity was also assessed.ResultsThe operation was successfully completed on all patients for the ipsilateral and bilateral lesions. Totally, 71.1% of mian lesions was mostly removed by lobectomy, and the completion rate of video-assisted thoracoscopic surgery (VATS) was 69.1% (67/97); 80.4% of secondary lesions were mostly removed by wedge resection, and the completion rate of VATS was 71.1% (69/97). The incidence of grade 3 or higher complications after unilateral or bilateral surgery was 12.8% and 5.3%, respectively. Postoperative pathology confirmed that the main lesions were malignant in 65 patients (67.0%), mainly adenocarcinoma (63.1%), of which 43.1% were in the stage Ⅰ; 32 patients were benign, mainly tuberculoma (56.3%). There were 29 patients of malignant secondary lesions, 67 benign, and 1 both benign and malignant; the pathological agreement rate of primary and secondary lesions was 54.6% (lung cancer metastases in the lung and all the benign). When the primary lesion was malignant with its diameters of <3 cm, 3-<5 cm, 5-7 cm, >7 cm, the metastatic rate of secondary lesions was 42.5%, 15.8%, 20.0%, 0, respectively. When the primary lesion was malignant with lymph node metastasis, the probability of the secondary lesion being a metastatic tumor was higher than that without lymph node metastasis (46.7% vs. 30.0%, P>0.05). When the primary lesion was malignant and the primary and secondary lesions were located in the same lobe, the secondary lesions were more likely to metastasize (54.5%), while when they were located on different lobes on the same side or different sides, the secondary lesions were more likely to be benign (58.1%, 72.7%), and the possibility of metastasis was small ( 32.6%, 9.1%). When the primary lesion was benign and clinical differential diagnosis was difficult, the secondary lesion was benign.ConclusionFor synchronous multiple pulmonary nodules, the diameter of the primary lesion is large, the metastatic rate of secondary lesions tends to decrease. In ipsilateral synchronous multiple pulmonary nodules, especially with node metastasis, the risk of metastatic nodule increases. Bilateral surgical resection does not significantly increase the perioperative morbidity.

Objective To study the relationships between expressions of somatostatin receptor subtypes（SSTR1-SSTR5） and angiogenesis in colorectal cancer. Methods The expressions of SSTR1-SSTR5, VEGF, and CD34 in the paraffin sections of colorectal cancer tissues from 127 cases were detected by the standard streptavidin-peroxidase (SP) technique. CD34 was used as a marker to account microvessel density (MVD) in colorectal cancer tissues. The relationships between the expressions of SSTR1-SSTR5 and VEGF expression, or MVD were analyzed. Results The positive expression rate of SSTR1, SSTR2, SSTR3, SSTR4, and SSTR5 was 64.6% （82/127）, 36.2% （46/127）, 18.9% （24/127）, 18.9% （24/127）, and 38.6% （49/127） in colorectal cancer tissues, meanwhile, the positive expression rate of VEGF was 63.8% （81/127） and MVD was (34.67±16.62)/HP in colorectal cancer tissues. The positive expression rate of VEGF (47.8%， 22/46) and MVD 〔(29.00±15.32)/HP〕 in colorectal cancer tissues with SSTR2 positive expression were significantly lower than those in colorectal cancer tissues with SSTR2 negative expression 〔72.8%， 59/81； (37.90±16.56)/HP〕, Plt;0.05. There were no relationships between SSTR1, SSTR3, SSTR4, and SSTR5 expression and VEGF expression or MVD （Pgt;0.05）. Conclusion The positive expression of SSTR2 is related with angiogenesis in colorectal cancer tissues.
【Abstract】Objective To analyze the function of BAG3 in antiapoptosis and chemotherapy resistance induction process of pancreatic cancer.Methods The expressions of BAG-3 in pancreatic cancerous tissues of patients with chemotherapy and those without chemotherapy before resection were determined by immunohistochemistry. The expression difference of BAG-3 protein 18 hours after cultured with chemotherapy drugs (concentration of drugs: 5-FU 50 μg/ml, MMC 0.5 μg/ml, EADM 1.5 μg/ml) of 3 pancreatic cancer cell lines （MIACaPa-2, PANC-1, SW1990） was measured through Western blotting method.Results The median positive rate of pancreatic cancer tissue from patients accepted chemotherapy before resection was higher than those not accepted chemotherapy, but there wasn’t significant difference. Eighteen hours after cultured with drugs, the level of BAG-3 of this three cell lines had significant increased compared with control group (P＜0.05). Conclusion Chemotherapy induces elevation of BAG-3 expression of pancreatic cancer. The upregulate of BAG-3 may associate with the chemotherapy resistance induced by drugs.
