Background

Liposarcoma is the most common soft tissue sarcoma, which comprises around 20% of soft tissue sarcoma. While diverse therapeutic approaches exist for liposarcoma, the primary goal remains the achievement of effective local disease control. Wide resection of liposarcoma is the cornerstone of treatment. Radiotherapy is often employed as an adjuvant measure to enhance the local disease control. At Hospital Kuala Lumpur, the treatment protocol includes R0 resection and followed by adjuvant radiotherapy. This study aims to review the demographic characteristic of liposarcoma patients and evaluate the efficacy of their treatment based on the treatment protocol.

Method and material

This is a retrospective cohort study. A total of 72 patients (male/female = 43/29) were included in this study. Recorded parameters included the histologic subtype, tumor location, treatment modality, resection margin, radiotherapy status, and occurrences of local recurrence and metastasis.

Result

Histopathological examination revealed a varied spectrum of liposarcoma subtypes, with the predominant subtype being atypical lipomatous tumor (n = 35), followed by myxoid liposarcoma (n = 32), two cases of dedifferentiated liposarcoma, and three cases of pleomorphic liposarcoma. Of these patients, 69 underwent resection, while three necessitated amputations. Total 62 achieving negative and 10 cases had R1 margins. Adjuvant radiotherapy was administered in 58 cases. Overall, the local recurrence was observed in only six cases.

Conclusion

This study emphasizes that achieving R0 resection is the fundamental approach in the treatment of liposarcoma and is able to minimize the risk of local recurrence.

背景脂肪肉瘤是最常见的软组织肉瘤，约占软组织肉瘤的 20%。虽然脂肪肉瘤的治疗方法多种多样，但首要目标仍然是实现有效的局部疾病控制。广泛切除脂肪肉瘤是治疗的基础。放疗通常被用作辅助措施，以加强对局部疾病的控制。吉隆坡医院的治疗方案包括 R0 切除术和辅助放疗。本研究旨在回顾脂肪肉瘤患者的人口统计学特征，并根据治疗方案评估其疗效。本研究共纳入 72 例患者（男/女=43/29）。结果组织病理学检查显示脂肪肉瘤亚型多样，主要亚型为非典型脂肪瘤（35 例），其次为肌样脂肪肉瘤（32 例），2 例为去分化脂肪肉瘤，3 例为多形性脂肪肉瘤。在这些患者中，69 例接受了切除手术，3 例需要截肢。共有 62 例达到阴性，10 例边缘为 R1。58例患者接受了辅助放疗。总的来说，只有6例患者出现了局部复发。结论这项研究强调，实现R0切除是治疗脂肪肉瘤的基本方法，能够将局部复发的风险降至最低。

Introduction

The diagnosis and treatment of breast cancer have tremendously changed in the last decades improving the survival and quality of life of the patients. Adherence to clinical practice guidelines in oncology significantly improves patients’ recurrence-free and overall survival. Nowadays, no national registry/database for breast cancer patients is available. This study aims to perform a nationwide analysis of the breast cancer guidelines adherence in Bulgaria, in particular regarding the diagnostic methods for histological confirmation and the types of radical surgery performed using an artificial intelligence (AI) powered software.

Materials and methods

We analyzed data from January 2019 to August 2023 nationwide using the platform with access to anonymized medical information from Bulgaria's leading territorial oncology hospitals. A total of 13,790 patients met the inclusion criteria.

Results

The gold standard diagnostic tool, CNB, was done in 5427 patients (39.35%), an intraoperative frozen section was performed as a method for confirmation of breast cancer in 6257 patients (45.37%) and the standard technique for lymph node evaluation, sentinel lymph node biopsy, was done in 357 patients (2.99%).

Conclusion

In Bulgaria, there are still difficulties in achieving comparable rates of core-needle biopsy for the diagnosis of breast cancer and we have demonstrated unacceptably high rates of frozen section use for intraoperative diagnosis of breast cancer. Breast-conserving surgery is widely accepted and available, but still, the rates are lower than usual for developed countries. The rates of sentinel lymph node biopsy, however, are unreasonably low.

导言在过去的几十年中，乳腺癌的诊断和治疗发生了巨大的变化，提高了患者的生存率和生活质量。遵守肿瘤学临床实践指南可显著提高患者的无复发率和总生存率。目前，还没有针对乳腺癌患者的全国性登记/数据库。本研究旨在对保加利亚乳腺癌指南的遵守情况进行全国范围的分析，特别是使用人工智能（AI）驱动的软件进行组织学确认的诊断方法和根治手术的类型。材料和方法我们使用保加利亚主要地区肿瘤医院的匿名医疗信息访问平台，分析了2019年1月至2023年8月的全国数据。共有 13790 名患者符合纳入标准。结果5427 名患者（39.35%）采用了金标准诊断工具 CNB，6257 名患者（45.37%）采用了术中冷冻切片作为乳腺癌的确认方法，357 名患者（2.99%）采用了淋巴结评估的标准技术--前哨淋巴结活检。结论在保加利亚，核心针活检用于乳腺癌诊断的比例仍难以达到可比水平，而且我们已经证明冷冻切片用于乳腺癌术中诊断的比例高得令人无法接受。保乳手术已被广泛接受和使用，但其比例仍低于发达国家的一般水平。然而，前哨淋巴结活检率低得不合理。

Introduction

This investigation assessed whether the following factors were associated with radiographic local progression in bone metastases from renal cell carcinoma (RCC): (1) high-risk histologic features (2) lesional surgery (3) biologically effective dose (BED) of radiation therapy.

Methods and materials

A single-institution database identified all patients who underwent surgery and radiation therapy for bone metastases from RCC to the appendicular skeleton and pelvis from 2006 to 2016. Thirty-six patients underwent radiotherapy for 80 metastases. While all patients had surgical stabilization, 17/36 also had lesional surgery to address the metastatic lesion. Progression of each individual lesion was determined using the application of RECIST criteria to imaging at last follow-up.

Results

The rate of progressive disease was 8/25 (32%) in the high-risk group versus 5/55 (9%) in the standard-risk group (p = 0.019). The rate of progression among high-risk metastases undergoing lesional surgery was 0/9 versus 8/16 (50%) having non-lesional surgery (p = 0.0218). The rate of progression among standard-risk metastases undergoing lesional surgery was 1/16 (6%) versus 4/39 (10%) with non-lesional surgery (p = 1.00). High-risk histologic features (OR: 10.592, 95% confidence interval: 1.347–83.271, p = 0.025) and as well as a reduction in risk with every additional Gray of BED (OR: 0.902, 95% confidence interval: 0.827–0.984, p = 0.021) were found to predict progressive disease.

Conclusions

Bone metastases from renal cell carcinoma with high-risk histologic features are associated with less favorable response to radiotherapy than those with standard-risk histology. Delivery of a higher BED was associated with lower odds of progression.

导读：这项研究评估了以下因素是否与肾细胞癌（RCC）骨转移的放射学局部进展有关：（1）高危组织学特征（2）病变手术（3）放疗的生物有效剂量（BED）。方法和材料一个单一机构的数据库确定了2006年至2016年期间所有因RCC骨转移至阑尾骨骼和骨盆而接受手术和放疗的患者。36名患者因80处转移灶接受了放疗。虽然所有患者都接受了手术稳定治疗，但其中17/36的患者还接受了病灶手术来治疗转移病灶。结果高危组中疾病进展率为8/25（32%），而标准风险组为5/55（9%）（P = 0.019）。接受病变手术的高危转移灶中，疾病进展率为0/9，而接受非病变手术的为8/16（50%）（P = 0.0218）。接受病变手术的标准风险转移灶的进展率为1/16（6%），而接受非病变手术的标准风险转移灶的进展率为4/39（10%）（p = 1.00）。高风险组织学特征（OR：10.592，95% 置信区间：1.347-83.271，p = 0.025）和每增加一个 BED 格雷风险降低（OR：0.902，95% 置信区间：0.827-0.984，p = 0.结论与标准风险组织学相比，具有高风险组织学特征的肾细胞癌骨转移与放疗反应较差有关。较高的BED与较低的进展几率相关。

Background

We aimed to identify prognostic factors for mortality and survival in patients operated on for metachronous primary lung cancer (MPLC).

Materials and methods

The data of 67 non-small cell lung cancer patients with MPLC, diagnosed and operated upon between January 2000 and December 2015, were retrospectively analyzed.

Results

Of the 67 included patients, 63 (94%) were male and 4 (6%) were female. The overall survival rate after second surgery was 53.6% at 5 years and 34.1% at 10 years. The mean survival time was 64 months (95% confidence interval: 35–92 months). Adjuvant treatment improved survival (p = 0.039). Although the survival of grade N0 and N1 patients did not differ, four grade N2 patients exhibited poor survival (p = 0.02). Cox's regression analysis revealed that grade N2 disease decreased survival 5.3- fold, the absence of adjuvant treatment decreased survival 2 fold and pT4 grade decreased survival 3.4 fold.

Conclusions

New lung tumors may be detected during follow-up of lung cancer patients who have been definitively treated. In such cases, if extrapulmonary metastases and N2 lymphatic involvement are absent, there is no recurrence in the surgical margins of the first operation, and there is only one new tumor, we suggest that surgical treatment should be initially chosen for patients with adequate cardiopulmonary reserves regardless of the time of appearance of the second tumor, whether or not the histopathological type is the same as that of the first tumor.

背景我们的目的是确定因并发原发性肺癌（MPLC）而接受手术的患者的死亡率和生存率的预后因素。材料和方法我们对2000年1月至2015年12月期间确诊并接受手术的67例MPLC非小细胞肺癌患者的数据进行了回顾性分析。结果在纳入的67例患者中，63例（94%）为男性，4例（6%）为女性。第二次手术后，5年总生存率为53.6%，10年总生存率为34.1%。平均存活时间为64个月（95%置信区间：35-92个月）。辅助治疗提高了生存率（P = 0.039）。虽然N0级和N1级患者的生存率没有差异，但4名N2级患者的生存率较低（P = 0.02）。Cox回归分析显示，N2级患者的生存率降低了5.3倍，未接受辅助治疗的患者生存率降低了2倍，pT4级患者的生存率降低了3.4倍。在这种情况下，如果没有肺外转移和 N2 淋巴受累，第一次手术的手术边缘没有复发，并且只有一个新的肿瘤，我们建议无论第二个肿瘤出现的时间长短，组织病理学类型是否与第一个肿瘤相同，心肺储备充足的患者都应首先选择手术治疗。

Background

During a pancreaticoduodenectomy, Feeding Jejunostomy (FJ) is frequently placed to improve postoperative nutrition. Our aim is to ascertain the effects of the FJ tube after pancreaticoduodenectomy.

Methods

Prospective analysis was performed on all patients who underwent concurrent FJ after pancreaticoduodenectomy (Whipples surgery) between 2022 and 2023. On POD 1, FJ feeds were frequently initiated. After the patient had taken enough oral feeds, the jejunostomy feeds were stopped. Frequency and mean were used to represent the data.

Results

A total of 48 patients underwent pancreaticoduodenectomy with concomitant FJ. A total of 35 (72.9%) were men and the mean age was 49.2 years. The majority (28, 58.3 %) of these patients had cancer head of the pancreas as an indication for surgery. Only 13 out of 48 (27%) patients required nutrition supplementation through FJ on POD 10. Only 1 out of 48 (2%) patients required FJ feeds on POD 30. None of these patients had tube-related complications in the 30-day postoperative period. There was a single FJ-related mortality in the 30-day postoperative period due to pulmonary embolism. The patients, who required prolonged FJ feeds had grade C pancreatic leaks, delayed gastric emptying, and surgical site infection.

Conclusion

The routine use of concurrent FJ in patients undergoing pancreaticoduodenectomy has a good outcome, especially for those who require prolonged postoperative nutritional supplementation because of grade c pancreatic leak and delayed gastric emptying.

背景在胰十二指肠切除术中，为了改善术后营养状况，通常会放置进食空肠造口（FJ）。我们的目的是确定胰十二指肠切除术后 FJ 管的效果。方法我们对 2022 年至 2023 年期间胰十二指肠切除术（Whipples 手术）后同时接受 FJ 的所有患者进行了前瞻性分析。在 POD 1，FJ 喂养经常被启动。在患者口服足够的饲料后，停止空肠造口喂养。结果共有 48 名患者接受了胰十二指肠切除术，并同时进行了 FJ。其中 35 例（72.9%）为男性，平均年龄为 49.2 岁。其中大部分患者（28 人，占 58.3%）的手术指征是胰头癌。48 名患者中只有 13 名（27%）需要在 POD 10 通过 FJ 补充营养。48 名患者中只有 1 名（2%）需要在 POD 30 日进行 FJ 喂食。这些患者在术后 30 天内均未出现与管道相关的并发症。术后 30 天内，有一名患者因肺栓塞而死亡。结论对接受胰十二指肠切除术的患者常规使用同期 FJ 有良好的效果，尤其是对那些因 C 级胰漏和胃排空延迟而需要术后长期营养补充的患者。

Background

Colorectal cancer (CRC) is one of the most common tumors worldwide, with rising numbers of elderly patients affected. Nutritional status significantly influences tumor prognosis. We aimed to investigate the association of subcutaneous and visceral adipose tissue and skeletal muscle mass with the prognosis of the oldest-old patients with CRC, after surgery.

Patients

We retrospectively reviewed 210 patients >75 years who underwent surgical treatment at the Department of Gastrointestinal Surgery, Beijing Hospital, between December 2010 and December 2020.

Materials

Subcutaneous adipose, visceral adipose, and skeletal muscle areas were measured using BMI_CT. The cut-off values of the CT measurements were then confirmed using receiver operating characteristic (ROC) curve analysis.

Results

Subcutaneous adipose tissue index (SATI), visceral adipose tissue index (VATI), and total adipose tissue index (TATI) were significantly associated with sex and BMI. Notably, the oldest-old CRC patients with high SATI, VATI, and TATI scores exhibited significantly higher rates of wound complications and reduced postoperative hospitalization durations. Intriguingly, patients with high VATI and TATI demonstrated significantly better 5-year Overall survival (OS), Cancer-specific survival (CSS), and Disease-free survival (DFS) than patients in the other groups. Similar results were observed in patients with a high visceral-to-subcutaneous fat ratio (VSR) and skeletal muscle index (SMI) scores.

Conclusion

Significantly improving skeletal muscle content while concurrently managing the total adipose content, especially visceral adipose tissue, may aid in extending the survival time of oldest-old patients with CRC after surgery.

背景直肠癌（CRC）是全球最常见的肿瘤之一，老年患者人数不断增加。营养状况对肿瘤预后有重要影响。我们旨在研究皮下和内脏脂肪组织及骨骼肌质量与高龄 CRC 患者术后预后的关系。患者我们回顾性研究了 2010 年 12 月至 2020 年 12 月期间在北京医院胃肠外科接受手术治疗的 210 例 75 岁患者。结果皮下脂肪组织指数（SATI）、内脏脂肪组织指数（VATI）和总脂肪组织指数（TATI）与性别和体重指数显著相关。值得注意的是，SATI、VATI 和 TATI 分数高的高龄 CRC 患者的伤口并发症发生率明显更高，术后住院时间也更短。有趣的是，VATI 和 TATI 分数高的患者的 5 年总生存期（OS）、癌症特异性生存期（CSS）和无病生存期（DFS）明显优于其他组别。结论在控制总脂肪含量（尤其是内脏脂肪组织）的同时，显著改善骨骼肌含量可能有助于延长年龄最大的 CRC 患者的术后生存时间。

Objectives

Present study aims to explore the surgery patterns and survival of T4N2 non-small cell lung cancer (NSCLC) in real-world condition.

Materials and methods

Clinical stage T4N2 NSCLC patients in Surveillance, Epidemiology and End Result Program were extracted. Cox regression was used for calculation of hazard ratio (HR) and confidence interval (CI), and landmark analysis was used for survival test at different cut-off time points.

Results

There were 1445 eligible patients included, of which 306 patients received surgery alone, 390 patients received induction therapy, and 749 patients received adjuvant therapy. For resection types, 1210 patients received lobectomy and 235 received pneumonectomy. Among patient receiving induction therapy, the overall survival (OS) HRs of pneumonectomy at 1-year, 3-year, 5-year, and 8-year cut-off points were 1.330, 0.972, 1.231, and 1.332 (P = 0.708, 0.972, 0.281 and 0.145), respectively, and cancer-specific survival (CSS) HRs at these landmark points were 2.386, 1.231, 1.455, and 1.480 (P = 0.293, P = 0.409, 0.059 and 0.056), respectively. Among patients receiving adjuvant therapy, the OS HRs of pneumonectomy at 1-year and 8-year cut-off points were 1.570 and 1.274 (P = 0.050 and 0.087), respectively, and CSS HRs at these landmark points were 1.493 and 1.284 (P = 0.096 and 0.094), respectively. Both OS and CSS of patients receiving lobectomy were superior than pneumonectomy at 3-year and 5-year in this cohort. For patients receiving surgery alone, pneumonectomy resulted in inferior survival than lobectomy at all cut-off points (all P < 0.05).

Conclusions

Surgery after induction therapy is still an optional choice for T4N2 NSCLC, and pneumonectomy should not be excluded from treatment strategy.

目的本研究旨在探讨真实世界中T4N2非小细胞肺癌（NSCLC）的手术模式和生存情况。材料和方法抽取监测、流行病学和最终结果项目中临床分期为T4N2的NSCLC患者。结果共纳入 1445 名符合条件的患者，其中 306 名患者接受了单纯手术治疗，390 名患者接受了诱导治疗，749 名患者接受了辅助治疗。就切除类型而言，1210 名患者接受了肺叶切除术，235 名患者接受了肺切除术。在接受诱导治疗的患者中，肺切除术在1年、3年、5年和8年截断点的总生存率（OS）分别为1.330、0.972、1.231和1.332（P = 0.708、0.972、0.281和0.145），这些标志点的癌症特异性生存（CSS）HRs分别为2.386、1.231、1.455和1.480（P = 0.293、P = 0.409、0.059和0.056）。在接受辅助治疗的患者中，肺切除术在1年和8年截断点的OS HR分别为1.570和1.274（P = 0.050和0.087），在这些标志点的CSS HR分别为1.493和1.284（P = 0.096和0.094）。在该队列中，接受肺叶切除术的患者在3年和5年的OS和CSS均优于肺切除术。结论对于T4N2型NSCLC，诱导治疗后手术仍是一种可选方案，不应将肺切除术排除在治疗策略之外。
