OBJECTIVETo compare the total thyroidectomy or subtotal resection and gland lobe and isthmus lobectomy as initial treatment to TNM stage I and II differentiated thyroid cancer. The difference between recurrence rate and surgical complications were analysed.
METHODSThe literatures published between 1972-2012 were searched in Pubmed, Medline, Wanfang database, Chinese Biomedical Literature Database, Chinese scientific Journals database and China National Knowledge Infrastructure. According to the inclusion and deletion criteria, 17 articles were included to compare the postoperative recurrence and complications in randomized controlled or case-control studies, involving 13 articles in recurrence rate and 11 articles in complications.RevMan5.0 software package was used to perform meta-analysis.
RESULTSThirteen articles involved with the recurrence rate, the total case number was 3511. Among these cases, 414 recurred, overall recurrence rate was 11.59%, of which, 150 recurred cases in total or subtotal resection group (experimental group), the recurrence rate was 6.51%; 264 recurred cases in gland lobe lobectomy plus isthmus group (control group), the recurrence rate was 21.83%. Comparing the two groups, the odds ratio (OR) and their 95% confidence interval (95%CI) was 0.26 [0.21,0.33], Z value was 11.33, P < 0.01, which showed that the recurrence rate in experimental group was significantly lower than that in control group.Eleven articles involved with the complications, the total case number was 2388, 166 cases had postoperative complications. The complication rate was 6.95%, of which, 109 cases in experimental group, the complication rate was 8.52%; 57 cases in control group, the complication rate was 5.15%. Compared with the two groups, OR values and their 95%CI was 3.63 [2.47, 5.33], Z was 6.58, P < 0.01, the experimental group had significantly higher incidence of complications.
CONCLUSIONFor I and II differentiated thyroid cancer, total thyroidectomy or subtotal resection may reduce the chance of recurrence, but the postoperative complications is higher; while gland lobe and isthmus lobectomy has lower postoperative complications, but may increase the risk of relapse.

INTRODUCTION:
The introduction of laparoscopic surgery has changed abdominal surgery. We evaluated the evolution and changing trends associated with adoption of laparoscopic liver resection (LLR) and the experience of a surgeon without prior LLR experience.
METHODS:
A retrospective review of 310 patients who underwent LLR performed by a single surgeon from 2011 to 2020 was conducted. Exclusion criteria were patients who underwent laparoscopic liver surgeries such as excision biopsy, local ablation, drainage of abscesses and deroofing of liver cysts. There were 300 cases and the cohort was divided into 5 groups of 60 patients.
RESULTS:
There were 288 patients who underwent a totally minimally invasive approach, including 28 robotic-assisted procedures. Open conversion occurred for 13 (4.3%) patients; the conversion rate decreased significantly from 10% in the initial period to 3.3% subsequently. There were 83 (27.7%) major resections and 131 (43.7%) resections were performed for tumours in the difficult posterosuperior location. There were 152 (50.7%) patients with previous abdominal surgery, including 52 (17.3%) repeat liver resections for recurrent tumours, and 60 patients had other concomitant operations. According to the Iwate criteria, 135 (44.7%) were graded as high/expert difficulty. Major morbidity (>grade 3a) occurred in 12 (4.0%) patients and there was no 30-day mortality. Comparison across the 5 patient groups demonstrated a significant trend towards older patients, higher American Society of Anesthesiologists (ASA) score, increasing frequency of LLR with previous abdominal surgery, increasing frequency of portal hypertension and huge tumours, decreasing blood loss and decreasing transfusion rate across the study period. Surgeon experience (≤60 cases) and Institut Mutualiste Montsouris (IMM) high grade resections were independent predictors of open conversion. Open conversion was associated with worse perioperative outcomes such as increased blood loss, transfusion rate, morbidity and length of stay.
CONCLUSION
LLR can be safely adopted for resections of all difficulty grades, including major resections and for tumours located in the difficult posterosuperior segments, with a low open conversion rate.

OBJECTIVE:
To investigate the clinicopathologic features and prognostic factors in oral basaloid squamous cell carcinoma.
METHODS:
Retrospective analysis of oral basaloid squamous cell carcinomas patients who underwent tumor resection during the period from January 2002 to December 2020 in the authors' hospital, especially the clinicopathologic characteristics of 28 cases with confirmed diagnosis and follow-up data. Immunohistochemistry was performed to define the helpful markers for differentiation diagnosis. The factors influencing the prognosis were evaluated based on Kaplan-Meier method.
RESULTS:
The tongue and mouth floor (11 cases, 39.3%) were the most frequently involved sites, followed by gingiva (6 cases, 21.4%), buccal (5 cases, 17.9%), palate (4 cases, 14.3%), and oropharynx (2 cases, 7.1%). The majority of basaloid squamous cell carcinomas were in advanced stage, with 12 cases in stage Ⅱ and 16 cases in stages Ⅲ-Ⅳ. Twelve of 28 patients were identified to have cervical lymph node metastasis, which was confirmed by histopathological examination. The incidence rate of lymph node metastasis was 42.9% (12/28). Nine tumors recurred, with one metastasized to the lung. At the meantime, the 28 conventional squamous cell carcinomas were matched with the same stage, among which 13 cases were identified with cervical lymph node metastasis. The incidence rate of lymph node metastasis was 46.4% (13/28). Five cases recurred, with two cases that metastasized to the lung and one to the brain. The 5-year overall survival rates of the basaloid squamous cell carcinoma and conventional squamous cell carcinoma patients were 54.6% and 53.8%, respectively. Histopathologically, basaloid cells consisted of tumor islands without evident keratinization but frequently with comedo-like necrosis within the tumor islands. CK5/6 and P63 exhibited strongly positive in all the 28 cases, whereas neuroendocrine markers, CgA and Syn, were negative. Eight cases positively expressed P16; one case showed focal SOX10 positive but CK7 negative.
CONCLUSION
The majority of oral basaloid squamous cell carcinomas present in advanced stage with a high tendency to lymph node metastasis, but the overall survival rates are not significantly different from conventional squamous cell carcinomas matched with the same stage. The human papilloma virus (HPV), as HPV-positivity rate is high, correlates to good prognosis. In addition, CK7 & SOX10 immunohistochemistry could contribute to differential diagnosis for basaloid squamous cell carcinoma with solid adenoid cystic carcinoma.

OBJECTIVE:
To investigate the safety and efficacy of reinforced radiculoplasty in the treatment of symptomatic sacral Tarlov cysts (TCs).
METHODS:
A retrospective analysis was performed on the clinical data and follow-up data of 71 patients with symptomatic sacral TCs who underwent reinforced radiculoplasty in the Neurosurgery Department of Peking University Third Hospital from June 2018 to March 2021. All the operations were performed under neuroelectrophysiological monitoring. Intraoperative cyst exploration, partial resection of the cyst wall, narrowing of the leak, nerve root sleeve radiculoplasty and artificial dural reinforcement were performed. The incidence of postoperative complications and new neurological dysfunction was analyzed. Visual analogue scale (VAS) was used to assess the changes of pain before and after surgery. The Japanese Orthopedics Association (JOA) low back pain score was used to evaluate the changes in nerve function before and after surgery.
RESULTS:
In the study, 71 patients had 101 TCs, 19 (18.8%) TCs originated from the left S1 nerve, 26 (25.7%) originated from the left S2 nerve, 3 (3.0%) originated from the left S3 nerve, 14 (13.9%) originated from the right S1 nerve, 33 (32.7%) originated from the right S2 nerve, 6 (5.9%) originated from the right S3 nerve, all the TCs underwent reinforced radiculoplasty. Deep infection (1 case), subcutaneous effusion (1 case), fat li-quefaction (1 case) and urinary tract infection (4 cases) were recorded postoperatively. The patients were followed up for 12-43 months (median, 26 months). Two cases had new urinary retention after operation, and the catheter was removed at the end of the first and second months respectively. One case had new fecal weakness, which improved after 3 months. Compared with preoperation, VAS decreased significantly at the last follow-up [median, 6 (4-9) vs. 1 (0-5), Z=-7.272, P < 0.001], JOA score increased significantly [median, 20 (16-25) vs. 27 (18-29), Z=-7.265, P < 0.001]. There were 18 cured cases (25.4%), 41 excellent cases (57.7%), 8 effective cases (11.3%), and 4 invalid cases (5.6%). The total efficiency was 94.4% (67/71). Two (1.98%) cysts recurred.
CONCLUSION
For patients with symptomatic sacral TCs, reinforced radiculoplasty can significantly improve the pain and nerve function, which is safe and reliable.

BACKGROUND:
Pregnancy-associated breast cancer (PABC) is a special type of breast cancer that occurs during pregnancy and within 1 year after childbirth. With the rapid social development and the adjustment of reproductive policies in China, the average age of females at first childbirth is increasing, which is expected to lead to an increase in the incidence of PABC. This study aimed to accumulate clinical experience and to investigate and summarize the prevalence, diagnosis, and treatment of PABC based on large multicenter samples in China.
METHODS:
According to the Chinese Society of Breast Surgery, a total of 164 patients with PABC in 27 hospitals from January 2016 to December 2018 were identified. The pregnancy status, clinicopathological features, comprehensive treatment methods, and outcomes were retrospectively analyzed. Survival curves were plotted using the Kaplan-Meier method.
RESULTS:
A total of 164 patients of PABC accounted for 0.30% of the total number of cases in the same period; of which, 83 patients were diagnosed during pregnancy and 81 patients during lactation. The median age of PABC was 33 years (24-47 years). Stage I patients accounted for 9.1% (15/164), stage II 54.9% (90/164), stage III 24.4% (40/164), and stage IV 2.4% (4/164). About 9.1% (15/164) of patients were luminal A. Luminal B patients accounted the most (43.3% [71/164]). About 15.2% (25/164) of patients were human epidermal growth factor receptor 2 (Her-2) overexpression and 18.9% (31/164) of patients were triple-negative breast cancer. For pregnancy breast cancer, 36.1% (30/83) of patients received direct surgery and 20.5% (17/83) received chemotherapy during pregnancy. About 31.3% (26/83) chose abortion or induction of labor. The median follow-up time was 36 months (3-59 months); 11.0% (18/164) patients had local recurrence or distant metastasis and 3.0% (5/164) died.
CONCLUSIONS
It is safe and feasible to standardize surgery and chemotherapy for PABC.

OBJECTIVETo investigate the regular pattern and prognostic evaluation of patients with recurrent rectal cancer after resection.
METHODSThree hundred and fourteen cases with recurrent rectal cancer after resection treated between May 1979 and November 2006 were classified into three groups according to the recurrence intervals (<3 years, 3-5 years, >5 years). The survival rates and prognosis in the three groups were analyzed and compared retrospectively.
RESULTSOf the 314 patients, the cancer relapsed in 247 cases (78.7%) in less than 3 years, and the recurrence occurred predominantly within 2 years (207 cases, 65.9%) after the operation. The neoplasm in 41 cases (13.3%) recurred in 3-5 years after the operation, and 26 cases (8. 3%) in more than 5 years after the resection. Disease-free interval, Dukes stage, neoplasm gross type, histological type, T stage, lymphatic and distant metastasis were associated with the prognosis on univariate analysis. And disease-free interval and tumor Dukes stage were independent prognostic factors for survival rate on multivariate analysis. Disease-free interval and progression-free survival were related positively with survival time.
CONCLUSIONSThe rectal cancer patients should be followed-up intensively for 2 years after the operation and moderately from then on. Disease-free interval and progression-free survival could be taken as the best predictors of long-term cure and prognosis.

7.Epidemiological characteristics and inducing factors of gastric stump cancer.
Chinese Journal of Gastrointestinal Surgery 2018;21(5):498-501
Gastric stump cancer was initially defined as a carcinoma of the stomach occurring more than 5 years after surgery for gastric or duodenal benign disease. In recent years, as the number of total gastrectomy for benign disease has gradually decreased and the gastric cancer detection and operation rate have annually increased, residual recurrence of primary gastric cancer more than 10 years after gastric cancer surgery has also been considered as gastric stump cancer. The incidence of gastric stump cancer is increasing annually. The epidemiological characteristics of this form of cancer are also developing, and they show a higher incidence in males compared to females. The incidence has been affected following digestive tract reconstruction, and the risk increases in patients who undergo Billroth II( reconstruction. The interval of onset is related to the benign and malignant condition of primary disease, and the incidence increases after 10 years of early gastric cancer surgery. Lymph node metastasis pattern in gastric stump cancer is different from that in primary gastric cancer as the primary operation may destroy normal lymph flow. Many factors are known to cause gastric stump cancer, mainly duodenal gastric reflux, Helicobacter pylori infection, and gastric mucosal barrier dysfunction; however, the mechanism is not clear. It is expected to reduce the incidence of gastric stump cancer by taking precautionary measures against different inducements, which also has some guiding significance for the treatment and prognosis of gastric cancer.

To determine whether radical hysterectomy is necessary in the treatment of endometrial cancer patients with cervical involvement, we reviewed the medical records of women who underwent primary surgical treatment for endometrial carcinoma and selected patients with pathologically proven cervical invasion. Among 133 patients, 62 patients underwent extrafascial hysterectomy (EH) and 71 radical or modified radical hysterectomy (RH). The decision regarding EH or RH was made at the discretion of the attending surgeon. The sensitivity of pre-operative magnetic resonance imaging for cervical invasion was 44.7% (38/85). In RH patients, 10/71 (14.1%) patients had frankly histologic parametrial involvement (PMI). All were stage III or over. Eight of 10 patients had pelvic/paraaortic node metastasis and two showed extrauterine spread. In 74 patients with stage II cancer, RH was performed in 41 and PMI was not seen. Sixty-six (89.2%) patients had adjuvant radiation therapy and there were 3 patients who had developed recurrent disease in the RH group and none in the EH group (Mean follow-up: 51 months). Although these findings cannot conclusively refute or support the necessity of radical hysterectomy in patients with cervical extension, it is noteworthy that the risk of PMI seems to be minimal in patients with a tumor confined to the uterus without evidence of extrauterine spread.

9.Ewing''s sarcoma: fifteen years' experience at Angau Memorial Hospital
Papua New Guinea medical journal 1990;33(1):17-23
A retrospective study was carried out on Ewing's sarcoma as seen between 1973 and 1987 at the Cancer Treatment Centre, Angau Memorial Hospital, Lae, Papua New Guinea. Some striking differences were observed in the epidemiological indices and the clinical picture of this disease here, when compared with other centres in the world. Most notably, Ewing's sarcoma, hitherto a rare tumour in this country, seems to be on the increase. In addition, among the flat bones, involvement of the scapula was disproportionately high. The early response to treatment was similar to findings elsewhere, although the long-term patient follow-up in this series was not satisfactory enough to allow proper estimates of long-term survival rates. The most recently advocated approach to the management of Ewing's sarcoma, which emphasizes surgery in preference to radiotherapy for local disease control, and adjuvant chemotherapy for micrometastases, is outlined.

OBJECTIVE: To evaluate the recurrence rates and patterns of failure in patients with stage I endometrial carcinoma after surgical staging without adjuvant therapy. METHODS: Medical records of 229 patients with stage I endometrial carcinoma, treated with surgery alone between 2002 and 2010 at Siriraj Hospital were retrospectively reviewed. The primary objective of this study was recurrence rates. The secondary objectives were patterns of failure, disease-free survival, overall survival, and prognostic factors related to outcomes. RESULTS: During median follow-up time of 53.3 months, 11 recurrences (4.8%) occurred with a median time to recurrence of 21.2 months (range, 7.7 to 77.8 months). Vaginal recurrence was the most common pattern of failure (8/11 patients, 72.7%). Other recurrences were pelvic, abdominal and multiple metastases. Factors that appeared to be prognostic factors on univariate analyses were age and having high intermediate risk (HIR) (Gynecologic Oncology Group [GOG] 99 criteria), none of which showed significance in multivariate analysis. The recurrence rates were higher in the patients with HIR criteria (22.2% vs. 4.1%, p=0.013) or patients with stage IB, grade 2 endometrioid carcinoma (9.4% vs. 4.3%, p=0.199). Five-year disease-free survival and 5-year overall survival were 93.9% (95% CI, 89.9 to 5.86) and 99.5% (95% CI, 97.0 to 99.9), respectively. CONCLUSION: The patients with low risk stage I endometrial carcinoma had excellent outcomes with surgery alone. Our study showed that no single factor was demonstrated to be an independent predictor for recurrence.
