RESUMO
Objective@#To summarize the clinical anatomical features and surgical technique of the submental artery perforator flap (SMAPF), and to evaluate the outcome and value of the flap for oral cavity reconstruction after cancer ablation.@*Methods@#A total of 56 patients with oral cancer were included in this study. The modified SMAPF excluded the anterior belly of the digastric muscle and submental fatty tissue. The primary sites of malignancy were buccal mucosa (n=24), tongue (n=21), mandibular gingiva (n=6), mouth floor (n=3), soft palate (n=2).@*Results@#The flap size varied from 3 cm×5 cm to 5 cm×12 cm. Four flaps presented mild venous congestion, which was salvaged with conservative measures such as acupuncture and blood letting. Overall flap survival rate was 100%. The SMAPF with septocutaneous perforator was used in 49 cases and with musculocutaneous perforator in seven cases. External jugular vein and internal jugular vein provides venous drainage were applied in half cases respectively. All the patients showed a good recovery of tongue mobility and mouth opening with a follow-up of 3-41 months. Local recurrence was detected in one patient 4 months after operation.@*Conclusions@#The SMAPF is a reliable flap for oral cavity reconstruction with outstanding functional and aesthetic outcomes.
RESUMO
Objective@#To explore the oncological safety of immediate breast reconstruction after nipple-areola complex(NAC) sparing mastectomy(NSM+ IBR) in patients with early stage breast cancer, and to analyze the prognostic factors of NSM+ IBR.@*Methods@#From January 2004 to December 2015, the clinical data of 118 cases of stage Ⅰ-ⅡA breast cancer who had undergone NSM+ IBR in Tianjin Tumor Hospital were collected, comparing with 75 cases of Ⅰ-ⅡA breast cancer patients who had undergone immediate breast reconstruction after modified radical mastectomy (MRM+ IBR) at the same period. In addition to the prognosis of these two groups, the prognostic factors were also retrospectively analyzed.@*Results@#The median follow-up were 53 months in the NSM+ IBR group and 51 months in the MRM+ IBR group, respectively. In the NSM+ IBR group, local recurrence, distant metastasis, death and NAC necrosis occurred in 4, 6, 9 and 4 cases during 3 years after operation, respectively. The local recurrence rate (LRR) was 3.4%, 3-year disease-free survival (DFS) rate was 91.5%, and the overall survival (OS) rate was 92.4%. In the MRM+ IBR group, local recurrence, distant metastasis, and death occurred in 1, 4, and 3 cases during 3 years after operation, respectively. The LRR was 1.3%, 3-year DFS was 93.3%, whereas the OS rate was 96.0%. No statistical difference was noted between the two groups (all P>0.05). That HER-2 positive and molecular type correlated with the 3-year DFS (P<0.05) independently and molecular type correlated with OS (P<0.05) independently in the NSM+ IBR group.@*Conclusions@#NSM does not impair patients′ prognosis and could ensure oncological safety of patients with early stage breast cancer. IBR could improve female patients′ figure and ensure the quality of life. HER-2 status and molecular type are the independent prognostic factors of the 3-year DFS. Molecular type is the independent prognosis factor of OS.
RESUMO
Objective To investigate the short-term outcomes and oncological safety of laparoscopy resection for colorectal cancer. Methods Between January 2004 and March 2009, 35 patients with colorectal cancer underwent laparoscopic-assisted surgery in our hospital, among which 32 underwent radical resection, 1 underwent laparoscopic exploration, and 2 were converted to open surgery. These patients were allocated in the laparoscopic group. Same numbers of patients who underwent conventional open surgery during the same period of time were identified and allocated in the open group. Short-term data, including surgical time, intra-operative blood loss, intra-operative blood transfusion, length of incision, histopathological data, post-operative complications and post-operative functions, were collected and compared between the two groups. Results A total of 67 patients were enrolled (32 in both laparoscopy and open groups). The other 3 cases were analyzed separately (1 underwent laparoscopic exploration and 2 converted to open surgery). The two groups were well balanced as to age, gender, and TNM staging and location of tumour. Histopathologically, the laparoscopic approach was equal to conventional approach as regard to resection margin (distal margin, 5 cm vs 5 cm, P=0.664) and lymph node yield (7 vs 8, P=0.228). This study also showed a longer surgical time (250 min vs 180 min, P=0.006), but shorter length of incision (10 cm vs 20 cm, P<0.001), less demand of intra-operative blood transfusion (1 case vs 10 cases, P=0.003), reduced use of analgesics (12 cases vs 25 cases, P=0.004), shorter post-operative stay (9.5 days vs 11 days, P=0.008) and earlier recovery of bowel function of the laparoscopic group. There was no statistical difference of intra-operative blood loss (200 mL vs 200 mL, P=0.098), incidence of post-operative complications (8 cases vs 6 cases, P=0.545) and volume of post-operative negative drainage (507.5 mL vs 669.0 mL, P=0.475) between the two groups. Conclusions Though limited by a relatively small sample size, our study showed that laparoscopy approach for colorectal cancer is equal to open approach in terms of oncological safety and short-term outcome.
RESUMO
PURPOSE: Flexible rectal stent for obstructive colorectal cancer has an advantage of elective one stage operation after decompression. But, forceful expansion of stent may increase the possibility of tumor cell dissemination through lymph nodes and blood vessels. We studied the oncological safety of stent insertion in obstructive colorectal cancer. METHODS: From June 1996 to August 2001, the patients with stent insertion for obstructive colorectal cancer at Samsung Medical Center were retrospectively evaluated. Seventy- one patients had stent insertion for palliation or curative resection. Among these patients 15 patients underwent curative surgery after stent insertion (stent group). During the same period 25 patients underwent multi-staged operation after the decompressing colostomy or Hartman operation. (staged operation group). Statistical methods such as Fisher's exact test, 2-test, Kaplan-Meier method were used. RESULTS: There was no significant difference between two groups in terms of age, gender, tumor location, and stage. The median follow-up period was 21 months in stent insertion group and 29 months in staged operation group. Overall recurrence rate was 33.3% in stent insertion group and 32.0% in staged operation group. The 5-year survival rate in stent insertion group was higher than in staged operation group (75.8% vs. 48.3%). But there was no statistical significance (P>0.05 ). Disease free survival was 22.4 (6~51) months in stent insertion group and 27.8 (5~71) months in staged operation group. There was no significant difference either. CONCLUSIONS: There was no significant difference between two groups in survival rate, recurrence rate in short term result. Flexible rectal stent insertion can be considered as oncologically safe and useful treatment of obstructive colorectal cancer. But we think long term follow up and much more cases will be necessary to make a conclusion more definitively.
