Introduction: Cancer has caused more deaths than all known wars and catastrophes. Particularly speaking, breast cancer has become a pandemic that threatens to continue to spread. Objective: To describe the differences based on the results obtained from conservative and radical surgery as a treatment for breast cancer. Methods: An analytical, observational, descriptive and retrospective study was carried out with a universe of 177 female patients diagnosed with breast cancer in the general surgery service of Centro de Investigaciones Médico Quirúrgicas, of La Habana, Cuba. All of them received surgical treatment in the period from January 2011 to December 2016. Results: 92.09 percent of the patients studied had no history of breast pathology, while 36.72 percent had breast cancer as a family pathological history. Patients over 70 years of age predominated in both surgical techniques. In the group of 30-40 years of age only conservative techniques were performed. With respect to staging, there was a predominance of the disease in stage II. Overall survival at 5 years was higher than 90 percent, while the disease-free interval remained at similar values for both techniques. Conclusions: A greater amount of breast-conserving surgeries were performed in patients at earlier clinical stages of the disease, while overall survival of conservative procedures was slightly higher(AU)

Influencing factors of anxiety and depression in patients with secondary lower extremity deep venous thrombosis after radical cervical cancer surgery / 中华健康管理学杂志

Objective:To investigate the influencing factors of anxiety and depression in patients with secondary lower extremity deep venous thrombosis (LEDVT) after radical cervical cancer surgery.Methods:Retrospective analysis method was used, a total of 92 patients with anxiety and/or depression secondary to LEDVT after radical cervical cancer surgery admitted to the People′s Hospital of Xinjiang Uygur Autonomous Region from June 2019 to June 2022 were included as the observation group, according to the presence of anxiety or depression, they were divided into anxiety group (65 cases) and depression group (58 cases) (some patients had both anxiety and depression). Another 90 patients who did not have anxiety or depression after radical cervical cancer surgery with secondary LEDVT were selected as the control group in the same period. The questionnaires of clinical data and disease cognition were designed to investigate the clinical data and disease cognition of patients, social support rating scale (SSRS) was used to assess the level of social support of patients, and univariate analysis was performed to identify the influencing factors of depression and anxiety in patients with secondary LEDVT after radical cervical cancer surgery.Results:The percentage of patients with self-pay, no children, unemployed or jobless, monthly family income <5 000 CNY, less social support, and disease awareness <80 scores in the anxiety group and depression group (36.92%, 67.69%, 69.23%, 66.15%, 46.15%, 70.77% and 34.48%, 68.97%, 72.41%, 65.52%, 44.83%, 68.97%) were higher than the control group (14.44%, 40.00%, 33.33%, 32.22%, 11.11%, 23.33%) (all P<0.01). The percentage of mixed thrombus, central thrombus, peripheral thrombus, bilateral thrombus, right thrombus, and left thrombus in the anxiety group and depression group (30.77%, 20.00%, 49.23%, 16.92%, 35.38%, 47.69% and 32.76%, 15.52%, 51.72%, 12.07%, 37.93%, 50.00%) were not significantly different from those in the control group (32.22%, 17.78%, 50.00%, 10.00%, 36.67%, 53.33%) (all P>0.05). Univariate analysis showed that self-pay, unemployed or jobless, no children, monthly family income <5 000 CNY, less social support, and disease awareness <80 scores were correlated with depression and anxiety status in patients with secondary LEDVT after radical cervical cancer surgery (all P<0.01). Conclusion:Depression and anxiety in patients with secondary LEDVT after radical cervical cancer surgery are related to self-pay, unemployed or jobless, no children, low monthly family income, less social support, and low disease awareness.

Clinical features and optimal treatment of primary urethral carcinoma / 现代泌尿外科杂志

【Objective】 To explore the clinical features and treatment outcomes of female urethral carcinoma so as to improve the awareness and prognosis of this rare malignant disease. 【Methods】 Clinical data of 8 cases of female urethral carcinoma treated during Jan. 2012 to Dec.2022 at the Department of Urology of Peking University People’s Hospital were retrospectively analyzed. The patients underwent urodynamic tests, cystourethroscopy and pathological biopsy to confirm the diagnosis. Traditional radical surgery was performed in 5 cases, and radical surgery for lower urethral cancer with bladder preservation was performed in 3 cases. 【Results】 The patients aged 36 to 68 years, with a mean of 53.75 years. Urinary obstruction, lower urinary tract symptoms and urethral masses were common manifestations. Urodynamic tests indicated bladder outlet obstruction. After surgical treatment, radical surgery for lower urethral cancer with bladder preservation showed advantages over traditional radical surgery in terms of intraoperative bleeding, operation time and postoperative hospital stay. 【Conclusion】 Female primary urethral carcinoma is rare but invasive. Early diagnosis and radical surgery are crucial for improving the prognosis. Radical surgery for lower urethral cancer with bladder preservation has better treatment outcomes and postoperative quality of life compared to traditional radical surgery. For such patients, symptoms should be closely monitored and timely diagnosis and treatment should be performed.

Clinical application of optical surface monitoring system in radiotherapy after radical mastectomy for left breast cancer / 中国辐射卫生

@#<b>Objective</b> To study the setup error under deep inspiration breath hold (DIBH) guided by optical surface monitoring system (OSMS) and free breathing (FB) FB1 and FB2 (without OSMS guidance, directly set up the body marker line by laser lamp) in radiotherapy after radical mastectomy for left breast cancer, and to provide a basis for individualized clinical target volume-planning target volume (CTV-PTV) expansion for the doctor in charge to delineate the target volume. <b>Methods</b> A total of 36 patients with left breast cancer after radical mastectomy were selected and divided into three groups, in which cone beam computed tomography (CBCT) images were taken in three states: DIBH, FB1, and FB2, respectively. CBCT and CT images were analyzed for registration; the absolute error data of linear displacement in the ventro-dorsal, cranio-caudal, and left-right directions were recorded, and the expanding margin was calculated. <b>Results</b> The translation errors in the ventro-dorsal, cranio-caudal, and left-right directions were (0.06 ± 0.22) cm, (0.05 ± 0.23) cm, and (0.01 ± 0.24) cm in the DIBH group, (0.07 ± 0.21) cm, (0.02 ± 0.23) cm, and (0.02 ± 0.21) cm in the FB1 group, and (0.07 ± 0.24) cm, (0.07 ± 0.34) cm, and (0.25 ± 0.09) cm in the FB2 group. The statistical results of the DIBH group and FB1 group in the ventro-dorsal, RTN, and ROLL directions were significantly different (<i>P</i> < 0.05). The statistical results of the FB1 group and FB2 group in the ventro-dorsal direction were significantly different. The relation of three groups in the value of margin of planning target volume was DIBH < FB1 < FB2 in the ventro-dorsal and cranio-caudal directions and FB1 < DIBH < FB2 in the left-right direction. <b>Conclusion</b> OSMS-guided DIBH radiotherapy in patients with left breast cancer after radical mastectomy can reduce the setup error and provide an important basis for individualized CTV-PTV expansion for the doctor in charge to delineate the target volume.

Resumen OBJETIVO: Comparar la cirugía radical con la cirugía conservadora de la fertilidad en mujeres con cáncer de ovario epitelial en estadio 1A-C con respecto a la tasa de recurrencia y las tasas de supervivencia. Además, evaluar los desenlaces reproductivos y obstétricos para las mujeres con cáncer de ovario epitelial en estadio I tratadas con una conducta conservadora de la fertilidad. PACIENTES Y MÉTODOS: Estudio prospectivo efectuado en pacientes con cáncer de ovario epitelial, estadio I, con edad ≤ 40 años. A las pacientes del grupo de preservación de la fertilidad se les practicó salpingooforectomía del lado del ovario afectado y una biopsia por incisión o escisión en cuña del ovario contralateral. A las pacientes del grupo de cirugía radical se les practicó la histerectomía total y salpingooforectomía bilateral. Para evaluar los desenlaces reproductivos y oncológicos se dio seguimiento a todas las pacientes durante cinco años. RESULTADOS: Se estudiaron 60 pacientes; las del grupo de cirugía de preservación de la fertilidad eran significativamente más jóvenes (30 ± 4 en comparación con 35 ± 5) (p < 0.001), el tamaño de sus tumores era más pequeño 3.4 ± 1.3 en comparación con 6.0 ± 2,6 (p < 0.001), de menor grado (p < 0.001). = 0.011), estadio más precoz (p < 0.001) y con más histología mucinosa que las pacientes del grupo de cirugía radical. No hubo diferencias estadísticamente significativas entre ambos grupos en cuanto a la recurrencia tumoral o las tasas de supervivencia. De 25 pacientes operadas para preservación de la fertilidad 18 de 25 intentaron quedar embarazadas. Se registraron 15 de 18 embarazos, incluidos 13 nacidos vivos, 1 aborto espontáneo y 1 muerte fetal intrauterina. CONCLUSIÓN: La cirugía conservadora de la fertilidad podría ser una alternativa adecuada a la cirugía radical para mujeres jóvenes con cáncer epitelial de ovario en estadio I.

Abstract OBJECTIVE: In the current study, we aimed to compare between radical surgery and fertility saving surgery in females with stage 1A-C EOC regarding recurrence rate and patients survival rates in addition to evaluating reproductive and obstetric outcomes for stage I EOC females who were managed by fertility saving surgery. PATIENTS AND METHODS: We prospectively identified 60 patients diagnosed with stage I EOC aged ≤ 40 years. Patients in the fertility-preservation group underwent salpingo-oophorectomy on the side of the affected ovary in addition to incisional biopsy or wedge excision of the ovary on the other side. Patients in the radical surgery group underwent total hysterectomy and bilateral salpingo-oophorectomy. We followed up all patients for 5 years to assess their reproductive and oncological outcomes. RESULTS: Patients in the fertility preservation surgery group were significantly younger (30 ± 4 versus 35 ± 5) (p < 0.001), their tumor sizes were smaller 3.4 ± 1.3 versus 6.0 ± 2.6 (p < 0.001), of lower grade (p = 0.011), earlier stage (p < 0.001) and has more mucinous histology than patients in the radical surgery group. There were no statistically significant differences between both groups regarding tumor recurrence or survival rates. Of 25 patients underwent fertility preservation surgery, 18/25 (72%) tried to get pregnant. 15/18 (83%) pregnancies were recorded, including 13 live births, 1 miscarriage, and 1 intrauterine fetal death. CONCLUSION: Fertility sparing surgery could be adequate alternative to radical surgery for young females with stage I EOC.

da Vinci robot system for radical surgery of lung cancer in elderly patients / 中国胸心血管外科临床杂志

@#Objective    To evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer. Methods    We retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared. Results    There was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021). Conclusion    The da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.

Comparison of oxycodone with sufentanil in transition analgesia after radical surgery of cervical cancer / 西安交通大学学报(医学版)

【Objective】 To compare the efficacy and safety of oxycodone and sufentanil in transition analgesia after radical surgery of cervical cancer under general anesthesia. 【Methods】 A randomized, double-blind study was conducted. We randomly divided 68 patients on radical surgery of cervical cancer under general anesthesia into two groups: Group S (sufentanil in transition analgesia) (n=35) and Group O (oxycodone in transition analgesia) (n=33). Patients in Group S received sufentanil (0.1 μg/kg for endoscopy procedures or 0.15 μg/kg for laparotomy procedures), whereas patients in Group O received oxycodone (0.1 mg/kg for endoscopy procedures or 0.15 mg/kg for laparotomy procedures) 30 min before the end of operation as transition analgesia. We recorded the time of consciousness recovery and extubation, RSS restlessness score, the number of cough times, Ramsay score, Numerical Rating Scale (NRS) at rest in extubation immediately (T0), 30 min after extubation (T1), 1 h after extubation (T2), 2 h after extubation (T3), 4 h after extubation (T4), 12 h after surgery (T5), 24 h after surgery (T6), and the incidence of adverse complications within 24 h after operation. 【Results】 Compared with those in Group S, patients in Group O showed shorter time of consciousness recovery (4.28±3.35 vs. 5.53±2.25, P=0.027), shorter time of extubation (5.92±3.67 vs. 8.09±2.49, P=0.001), lower RSS restlessness score (0.38±0.49 vs. 0.83±0.63, P<0.001), smaller number of cough times (0.96±0.78 vs. 1.34±0.93, P=0.026), lower Ramsay score (2.3±0.58 vs. 2.63±0.85, P=0.017), and lower NRS score at rest in T3 and T4 (2.64±0.63 vs. 3.14±0.66; 2.86±0.81 vs. 3.69±0.75) (P<0.001). The incidence of nausea and vomiting was lower in Group O than in Group S (9.09% vs. 20%; 3.03% vs. 11.43%). 【Conclusion】 Both oxycodone and sufentanil provide adequate pain relief in transitional analgesia after radical surgery of cervical cancer under general anesthesia. However, oxycodone shows longer analgesia, faster recovery, and a lower incidence of side effects than sufentanil.

Laparoscopic precise positioning for radical prostatectomy or bladder cancer reducing the risk of delayed recovery / 解剖学报

Objective To analyze the risk factors of delayed recovery after laparoscopic prostate or bladder cancer radical surgery, and to provide information for early clinical prevention. Methods Three hundred and twenty-two cases of patients who underwent laparoscopic radical prostatectomy or bladder cancer surgery from September 2016 to January 2019 were enrolled in this study. The clinical data and surgical data of the patients were collected, the incidence of postoperative recovery delay was counted, and the risk factors of delayed recovery were analyzed by Logistic regression analysis. Results Six-noe cases of delayed recovery of laparoscopic prostate or bladder cancer were detected, the incidence rate was 18.1% (61/327) ; Univariate analysis found that delayed laparoscopic recovery of prostate or bladder cancer after radical surgery and age, combined with coronary heart disease, diabetes, respiratory disease, anemia, smoking, alcohol consumption, American Society of Anesthesiologists (ASA) classification, anesthesia time, intraoperative infusion, location clarity of anatomical landmarks were related. There was a correlation between the total amount, combined epidural anesthesia and intraoperative blood transfusion (P<0.05). Multivariate logistic regression analysis found that the age, diabetes, respiratory disease, anemia, smoking, alcohol consumption, location clarity of anatomical landmarks and intraoperative total infusion were independent risk factors for delayed recovery after laparoscopic prostate cancer or radical surgery for bladder cancer (P<0.05). Conclusion There is correlation between delayed laparoscopic recovery of prostate cancer or bladder cancer after radical operation and age, diabetes, respiratory disease, anemia, smoking, alcohol consumption, location clarity of anatomical landmarks and intraoperative total infusion. Accurate anatomical location can reduce the risk of postoperative recovery delay. It is conducive to the recovery of the patients after operation, and the corresponding hospitalization time of the patients is greatly shortened.

Application Value of ctDNA-based MRD Dedection in Early Stage Non-small Cell Lung Cancer after Radical Surgery / 中国肺癌杂志

Lung cancer is the most common malignant tumor in the world, among which non-small cell lung cancer (NSCLC) accounts for about 85% of the total number of lung cancers. The 5-year overall survial (OS) of radical surgery NSCLC patients ranged from 92% in stage Ia1 to 26% in stage IIIb, and the continuously decreasing survival time made it a strong clinical need for precise adjuvant therapy to eradicate molecular residual disease (MRD). At present, circulating tumor DNA (ctDNA) as a molecular indicator of MRD has gradually moved from the laboratory to the clinic. The latest consensus proposes that ctDNA with abundance ≥0.02% can be stably detected in the peripheral blood of perioperative NSCLC patients, which is based on the possibility of ctDNA as an MRD indicator. MRD detection technology supports the possibility of monitoring after radical treatment of NSCLC, and ctDNA can predict the recurrence of the disease earlier than the imaging monitoring after treatment of NSCLC, providing valuable time for timely adjustment of adjuvant therapy. In the studies on early postoperative adjuvant therapy of NSCLC, different guidelines differ on whether appropriate adjuvant therapy should be carried out, while MRD can be used as a more accurate predictor to guide postoperative adjuvant therapy, so that patients can benefit from the disease treatment.

Objective To analyze the clinical characteristics and prognostic factors of rectal neuroendocrine neoplasm (r-NEN) with the maximum diameter of 1 cm to 2 cm,and to provide a theoretical evidence for selection of resection method.Methods From 1988 to 2015,the data of patients pathologically diagnosed as r-NEN with the maximum diameter less than 2 cm were selected from American surveillance,epidemiology,and end results (SEER) database with SEER * Stat 8.3.5 software.According to the resection method,the patients were divided into local resection group and radical resection group.T test and chi-square test were performed to compare the clinicopathological features.Kaplan-Meier survival analysis and Cox multivariate analysis were used to analyze the prognostic factors analysis.Results The maximum diameter of tumors of 1 831 patients with r-NEN was less than 1 cm,and that of 338 patients with r-NEN was between 1 cm and 2 cm.There were significant differences between two groups in tumor grade,tumor stage,T stage,lymph node metastasis,distant metastasis and resection method (x2 =7.120,144.728,86.296,133.096,42.842 and 52.048,all P ＜ 0.05).The prognosis of the former was better than that of the latter (x2 =11.590,P =0.001).Among the patients with r-NEN with the maximum diameter of 1 cm to 2 cm,279 (82.5％) patients received local resection and 59 (17.5％) patients underwent radical surgery.Propensity score matching was used to pair the r-NEN patients with the maximum diameter of 1 cm to 2 cm who received different resection methods,and 41 pairs of cases were enrolled.The results of univariate analysis showed that age and tumor grade affected the survival prognosis of patients with r-NEN of the maximum diameter of 1 cm to 2 cm (x2 =6.837 and 10.852,P =0.009 and 0.004).The results of Cox multivariate analysis indicated that age was an independent prognostic factor of patients with r-NEN of the maximum diameter of 1 cm to 2 cm (hazard ratio (HR) =1.110,95％ confidence interval (CI) 1.040 to 1.184,P =0.002).Analysis of subgroups without lymph nodes or distant metastases demonstrated that age (HR =1.101,95％ CI 1.042 to 1.162,P =0.001) and resection method (HR =3.128,95％ CI 1.003 to 9.754,P =0.049) were the independent factors.Conclusions Age is an independent factor of patients with r-NEN of the maximum diameter of 1 cm to 2 cm.Among the patients without lymph nodes or distant metastasis the younger cases and those with local resection have better prognosis.

Radical versus conservative surgical treatment of liver hydatid cysts: a meta-analysis / 医学前沿

To date, the efficacy of radical surgery (RS) versus conservative surgery (CS) for liver hydatid cysts (LHC) remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients.

Application of vascular replacement technique with allogenic blood vessel in radical resection for pancreatic carcinoma: a report of 33 cases / 中华外科杂志

Objective@#To analyze the application of vascular replacement technique with allogenic blood vessel in radical resection for pancreatic carcinoma.@*Methods@#The clinical data of 33 patients with vascular invasion of pancreatic carcinoma who underwent radical resection from April 2013 to April 2017 in Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital were retrospectively analyzed. There were 14 males and 19 females with age of (62.5±10.6)years(ranging from 35 to 78 years). Vascular replacement technique with allogenic blood vessel was used on all patients who underwent radical resection for pancreatic carcinoma. The operation procedure was made according to the specific location of the carcinoma, and the allogenic blood vessel was selected according to the type of vascular invasion. The matching vessel was selected for replacement to the patient who was invaded only one vessel. And the "Y" type of iliac vein was selected for replacement to the patient who was invaded the confluence of portal vein, splenic vein and superior mesenteric vein. After the operation, the patients were followed up by telephone and outpatient review.@*Results@#All of 33 patients were successfully completed the operations. There were 28 patients underwent pancreaticoduodenectomy with vascular replacement, and 5 patients underwent total pancreatectomy with vascular replacement. All the patients were confirmed pancreatic carcinoma and R0 resection according to the postoperative pathology. There were 16 patients with the carcinoma invasion the confluence of portal vein, splenic vein and superior mesenteric vein, 12 patients with the carcinoma invasion the superior mesenteric vein, and 5 patients with the carcinoma invasion the portal vein. There was no perioperative death in this group and no complications related to allogenic blood vessel. The incidence of postoperative complications was 18.2% (6/33), and the incidence of pancreatic fistula was 6.1% (2/33), all of which were biochemical fistula. There were 32 patients were followed up, and the follow-up rate was 96.9%. The median survival time was 14.6 months. The half-year, 1-year and 2-year survival rates were 75.6%, 37.6% and 27.4%.@*Conclusion@#The application of vascular replacement technique with allogenic blood vessel for pancreatic carcinoma has a great significance for improving the R0 resection rate and the prognosis of patients.
