Objective:To investigate the clinical effects of combined tissue flap transplantation in repairing giant chest wall defects.Methods:This study was a retrospective observational study. From August 2013 to December 2020, 31 patients with chest wall tumor or radiation ulcer after radical resection of chest wall tumor and conformed to the inclusion criteria were admitted to the Department of Breast Oncoplastic Surgery of Hunan Cancer Hospital, including 12 males and 19 females, aged 25-71 years. After resection of tumor or ulcer and wound debridement, the area of secondary chest wall defect was 300-600 cm 2 with length of 16-35 cm and width of 16-32 cm. According to the actual situation of the patients and the preoperative design, the chest wall defects were repaired with the flexible combination of perforator flaps and myocutaneous flaps from different donor sites, and the area of the combined tissue flap was 260-540 cm 2 with length of 20-30 cm and width of 13-20 cm. Free posteromedial thigh perforator flap+free anterolateral thigh myocutaneous flap were used in 2 patients, free deep inferior epigastric artery perforator flap+free anterolateral thigh myocutaneous flap were used in 5 patients, free deep inferior epigastric artery perforator flap+pedicled rectus abdominis myocutaneous flap+free anterolateral thigh myocutaneous flap were used in 7 patients, free deep inferior epigastric artery perforator flap+pedicled rectus abdominis myocutaneous flap+pedicled latissimus dorsi myocutaneous flap were used in 2 patients, and bilateral free anterolateral thigh myocutaneous flaps were used in 15 patients. For the remaining small area of superficial tissue defect after being repaired by combined tissue flaps, skin graft was used to repair or delayed local flap transfering was performed after the tissue flaps survived and edema subsided. The appropriate blood vessels in the donor and recipient sites were selected for anastomosis to reconstruct the blood supply of tissue flaps. The wounds in the donor sites of tissue flaps that can be directly sutured were sutured directly; for those that cannot be sutured directly, the skin grafting or delayed suture was performed. The anastomosis of blood vessels in the recipient sites, operation length, and postoperative hospital stay were recorded. The survivals of tissue flaps and skin grafts, the shape and texture of reconstructed chest wall, the wound healing, scar formation, and function of donor sites of tissue flaps, and the scar formation of the donor sites of skin grafts were observed after operation. Tumor recurrence and death of recurrent patients were followed up after operation. Results:The blood vessels in the recipient sites were anastomosed as follows: proximal internal thoracic vessels for 24 times, distal internal thoracic vessels for 12 times, trunk of thoracodorsal vessels for 4 times, anterior serratus branches of thoracodorsal vessels for 8 times, and thoracoacromial vessels for 12 times. The operation length was 6.0 to 8.5 hours, and the postoperative hospital stay was 9 to 21 days. Necrosis at the edge of partial tissue flaps occurred in 4 patients after operation, which healed after dressing change, and the tissue flaps and skin grafts of the other patients survived completely. The shape and texture of the reconstructed chest wall were good. Four patients had poor wound healing in the donor sites of abdominal tissue flaps, which healed after dressing change and local drainage. Only linear scar was left in the donor sites of all tissue flaps, and there was no obvious dysfunction in the donor sites of tissue flaps. Mild hypertrophic scar was left in the donor sites of skin grafts. During follow-up of 9 to 36 months after operation, 6 patients had tumor recurrence, and the recurrence time was 5 to 20 months after operation. After comprehensive treatment for patients with tumor recurrence, 3 patients died.Conclusions:Transplantation of combined tissue flaps in repairing the giant chest wall defects can shorten the time of total operation and hospital stay, and avoid multiple operations. After operation, patients had good chest wall appearance, with reduced tumor recurrence in patients with chest wall tumor.

As the global prevalence of obesity and the elderly population continues to increase,the in-cidence of sarcopenic obesity is also on the rise and becoming a global public health concern.Sarcopenic obesity not only increases the incidence of cancer,but is also associated with poor clinical outcomes in various cancers,such as surgical complications,increased risk of death,and possibly even an impact on chemotherapy as well.Therefore,sarcopenic obesity is emerging as an important indicator of prognosis in cancer patients.However,there are limited relevant studies on the association between sarcopenic obesity and cancer in China.This article reviews the definition and diagnosis of sarcopenic obesity,the clinical correlation between sar-copenic obesity and cancer,and the potential mechanisms,with a view to providing a reference for future clini-cal practice in China.

Objective:To evaluate whether whole brain radiation therapy(WBRT) could benefit small cell lung cancer (SCLC) patients with brain metastases.Methods:Clinical data of 245 patients who were diagnosed with extensive stage SCLC with brain metastases admitted to our hospital from 2010 to 2020 were retrospectively analyzed. Among them, 168 patients received WRBT (WBRT group, radiation dose: 30Gy in 10 fractions), and 77 patients did not receive WBRT (non-WBRT group). All patients received 4-6 cycles of chemotherapy, and the chemotherapy regimen included cisplatin (or carboplatin) plus etoposide. One hundred and fifteen patients received thoracic radiotherapy. The endpoint was overall survival after brain metastases(BM-OS). Chi-square test was used to compare categorical data, and stabilized inverse probability of treatment weighting(sIPTW) was used to match the factors between WBRT and no-WBRT groups. Survival analysis was estimated by Kaplan-Meier method, and the log-rank test was used to compare survival curves between two groups. Results:The median BM-OS for the whole group of patients was 9.1 months, and 10.6 months and 6.7 months in the WBRT and non-WBRT groups, respectively( P=0.003). After balanced influencing factors with stabilized sIPTW, significant difference still existed in BM-OS between two groups( P=0.02). In 118 patients with synchronous brain metastases, the median BM-OS in two groups were 13.0 months and 9.6 months( P=0.007); and in 127 patients with metachronous brain metastases, the median BM-OS were 8.0 months and 4.1 months( P=0.003). In 50 patients without extracranial metastases, the median BM-OS were 13.3 months and 10.9 months( P=0.259)in two groups; while in 195 patients with extracranial metastases, the median BM-OS were 9.5 months and 5.9 months( P=0.009)in two groups. Conclusions:WBRT could prolong the OS in extensive stage SCLC patients with brain metastases.

Objective:To evaluate the efficacy and safety of thoracic radiotherapy in the treatment of patients with extensive-stage small cell lung cancer (ES-SCLC) with different metastatic sites.Methods:A retrospective analysis was performed among 830 ES-SCLC patients who were admitted to our hospital from 2010 to 2019. They all received the first-line chemotherapy and had no progression after chemotherapy. 341 patients of them received thoracic radiotherapy after chemotherapy. The main endpoint was overall survival. The Chi-square test was used to compare the categorical data including gender and age, etc. Univariate survival analysis was estimated by Kaplan-Meier method and the log-rank test was used to compare the survival curves between two groups. A multivariate prognostic analysis was made by the Cox proportional hazard model.Results:In all the patients, the overall survival (OS) was 12.4 months. The patients with thoracic radiotherapy had significantly higher OS than the patients without thoracic radiotherapy (15.2 months vs.10.8 months, P<0.001). Thoracic radiotherapy significantly improved the OS in patients without liver metastasis (16.0 months vs.11.4 months, P<0.001) in the oligometastatic patients. But for the oligometastatic patients with liver metastasis, the OS benefit was not significant (14.2 months vs. 10.6 months, P=0.072). For polymetastatic patients without liver metastasis, thoracic radiotherapy offered significant OS benefits (14.5 months vs.10.9 months, P<0.001), but for the polymetastatic patients with liver metastasis, the OS was not improved with thoracic radiotherapy (10.2 months vs.9.2 months, P=0.715). Conclusions:In ES-SCLC patients, thoracic radiotherapy provides significant OS benefits in patients with oligometastases ES-SCLC without liver metastasis and for the liver metastatic patients may also benefit from thoracic radiotherapy based on the effectiveness of chemotherapy. In patients with multiple metastases, thoracic radiotherapy only improves the OS in patients without liver metastasis, but does not improve the prognosis in patients with liver metastasis.

【Objective】 To establish the reference interval of Thromboelastography(TEG)of healthy adult in Hainan, compare with the interval provided by the manufacturers, and analyze the influencing factors. 【Methods】 A total of 308 healthy adult volunteers were included according to the inclusion and exclusion criteria. The TEG was analyzed based on adequate quality control, and the reference interval of each parameter was calculated with 95% CI. 【Results】 The reference interval of these volunteers were R 4.27~9.20 min, K 1.60~3.83 min, Angle 44.22°~67.78°, MA 47.82~64.17 mm, CI -5.63~1.12 and G 4.58~9.03. 14.94% (46/308) of these volunteers had at least one index exceeded the reference interval provided by manufacturers. A total of 74 healthy volunteers were diagnosed with coagulation disorder, with the specificity at 79.22%. Significant differences of R, K, Angle, MA, CI, G were observed between males and females (P<0.05). Hypercoagulability was not associated with the age. 【Conclusion】 This study established a reference interval of TEG of healthy adults in Hainan, which provided reference for related clinical and basic science study.

【Objective】 To investigate the correlation between preoperative thromboelastography (TEG) parameters and routine coagulation tests of malignant tumor patients. 【Methods】 A total of 79 patients with malignant tumors, receiving preoperative TEG tests and routine coagulation tests between January 2019 and June 2020, were included. The correlation and regression between coagulation indexes and TEG parameters were analyzed. 【Results】 In patients with malignant tumors, the coagulation time(K) was negatively correlated with Plt and fibrinogen (FIB), while Angle, Ma, and G were respectively positively correlated with Plt and FIB. 【Conclusion】 There is a correlation between preoperative TEG parameters and routine coagulation tests in patients with malignant tumors. There is complementarity but not reciprocal substitutability between these two tests.

Objective To introduce the clinical experience of relaying anterolateral thigh (ALT)flap in the resurfacing of the donor defect after anteromedial thigh (AMT) flap transfer.Methods From February 2014 to December 2015,16 cases with oral carcinoma underwent radical resection,leaving tongue or mouth floor defects which were reconstructed by AMT perforator flaps.The flap size ranged from 7.5 cm ×4.5 cm to 13.0 cm × 7.5 cm [the patients was 45.6 years (range 31-72 years),body mass index (BMI) range 17.5-24.3 kg/m2].Flaps'width was on average 6.6 cm (ranging from 5 to 9 cm) with flap width-to-thigh circumference ratio being 12.5％ on average (ranging from 9.8％ to 15.7％).The flap donor sites were reconstructed with relaying ALT flap at the same stage,the flap size ranged from 7.5 cm × 4.0 cm to 12.0 cm x 7.0 cm.Results The AMT and ALT perforators existed consistently in all cases of this serie.All free AMT flaps and relaying ALT flaps survived uneventfully.All patients were followed up for 8-24 months with satisfied esthetic and functional results in recipient and donor sites.2-point discrimination distance of AMT flaps ranged from 7 to 14 mm,2-point discrimination distance of relaying ALT flaps ranged from 8 to 15 mm,the function of thighs were not affected.Conclusions The relaying ALT flap is an ideal choice to reconstruct the donor site of free AMT flap.

Objective: To investigate the application of free anteromedial thigh (AMT) perforator flap in the reconstruction of tongue defect after radical resection of tongue carcinoma. Methods: From September 2010 to January 2015, 57 cases with tongue carcinoma underwent radical resection, leaving tongue and mouth floor defects which were reconstructed by AMT perforator flaps at the same stage.These 57 eases included tongue carcinoma at lingual margin (n=36), at ventral tongue (n=15) and at mouth floor (n=6). Results: The size of AMT perforator flap ranged from 5.5 cm×4.0 cm to 7.5 cm×5.5 cm, the thickness of flap ranged from 1.0-1.7 cm.The length of pedicle from descending branch of lateral circumferential femoral artery is (8.2±0.6) cm, found in 28 cases.The length of pedicle from profunda femoral artery is (8.5±0.4) cm, found in 17 cases.The length of pedicle from femoral artery is (8.1±0.7) cm, found in 12 cases.All 57 perforator flaps survived uneventfully, the defects at donor site were closed directly in all cases. All patients were followed up for 12-24 months with satisfactory esthetic and functional results in reconstructed tongue. No local recurrence happened. Only linear scar left in the donor sites, the function of thighs were not affected. Conclusions The free AMT perforator flap is an ideal choice for reconstruction of the tongue and mouth floor defect after radical resection of tongue carcinoma.
