Differential Outcomes of VATS and Open Surgery in Lung Cancer Patients with Antecedent Oncological Diagnoses.

Primary lung cancer is a devastating disease with high morbidity and mortality rates. Patients with a previous oncological history may present with multiple comorbidities, unique clinical features, and unique outcomes after surgical intervention for primary lung cancer. This study aimed to compare the clinical features and outcomes of patients with a previous oncological history who underwent video-assisted thoracoscopic surgery (VATS) or open surgery (OS) for primary lung cancer. A retrospective analysis was conducted on 84 patients with a previous oncological history who underwent surgical intervention for primary lung cancer between January 2018 and January 2023. Among them, 55 patients underwent VATS, while 29 patients underwent OS. Demographic and clinical characteristics, perioperative variables, and postoperative outcomes of the two surgical groups were collected and compared. Most of the 84 patients were women (58.4%) with a high smoking prevalence (44.1%) and a median of 32.3 packs-year. The patients' histories were most predominant for gynecologic cancers (44.4%) and colorectal cancers (18.6%). The results showed that the VATS group had a significantly shorter median hospital stay than the OS group (6.0 days vs. 12.0 days, p-value < 0.001). Additionally, the VATS group had lower incidences of air leaks 24 h post-surgery (12.7% vs. 48.3%, p-value < 0.001) and intractable pain (3.6% vs. 17.2%, p-value = 0.031), as well as significantly lower operative times (270 min vs. 350 min, p-value = 0.046). However, there were no significant differences between the VATS and OS groups in overall survival (log-rank p-value = 0.447). Furthermore, although the 3-month survival was significantly higher in the VATS group (98.2% vs. 79.3%, p-value = 0.003), only one patient from the VATS group (1.8%) and two patients from the OS group (6.9%) were still alive five years after the intervention. In conclusion, VATS is a safe and effective surgical option for patients with a previous oncological history who require surgical intervention for primary lung cancer, with shorter operative times, shorter hospital stays, and lower rates of complications compared to those of OS patients, without compromising oncological outcomes. Nevertheless, both surgical options failed to improve the 5-year survival rate, probably due to the high prevalence of comorbidities and the burden of previous cancer in this population.

Indocyanine Green (ICG) and Colorectal Surgery: A Literature Review on Qualitative and Quantitative Methods of Usage.

Background: Due to its many benefits, indocyanine green (ICG) has gained progressive popularity in operating rooms (ORs) globally. This literature review examines its qualitative and quantitative usage in surgical treatment. Method: Relevant terms were searched in five international databases (1. Pubmed, 2. Sciencedirect, 3. Scopus, 4. Oxfordjournals, 5. Reaxys) for a comprehensive literature review. The main benefits of using ICG in colorectal surgery are: intraoperative fluorescence angiography; fluorescence-guided lymph node involvement detection and the sentinel technique; the fluorescent emphasis of a minute liver tumour, counting just 200 tumour cells; facilitation of fistula diagnosis; and tumour tattooing. This methodology can also be used with quantitative characteristics such as maximum intensity, relative maximum intensity, and in-flow parameters such as time-to-peak, slope, and t1/2max. This article concludes that fluorescence surgery with ICG and near-infrared (NIR) light is a relatively new technology that improves anatomical and functional information, allowing more comprehensive and safer tumour removal and the preservation of important structures.

Simultaneous Approach of Colo-Rectal and Hepatic Lesions in Colo-Rectal Cancers with Liver Metastasis - A Single Oncological Center Overview.

Introduction: Management of synchronous colorectal cancer with liver metastases (SCLM) is still on debate, regarding timing, indications and complications of the 3 strategies: classic approach (first tumor resection), simultaneous resection and reverse approach (liver first). A retrospective single-centre evaluation of synchronous approach was accomplished, focusing on surgical technique, indications and complications. Material and Methods: Between 2017 and 2020, 31 SCLM patients benefited from synchronously colorectal and hepatic approach: segmental colectomies/rectal resections, simultaneously with liver metastasectomies (associated with radiofrequency ablation). Post-therapeutic imaging monitoring was performed from every 3 - 6 months. There were no perioperative complications related to the combination of the procedures, low morbidity and zero postoperative mortality. Results: The follow-up period was 10 - 40 months: 13 patients had no evidence of recurrence, 10 had hepatic metastases in regression, 4 patients had signs of peritoneal carcinomatosis and 4 showed progression of liver disease; all patients were on chemotherapy. During follow-up 4 patients died. Conclusions: Experience shows that the simultaneous approach of recto-colic and hepatic resections in colo-rectal cancers is a safe procedure, with low morbidity, the limits being dictated by the size of the liver metastases. The results at long-distance must be drawn by further consistent trials.

A Decade of Therapeutic Challenges in Synchronous Gynecological Cancers from the Bucharest Oncological Institute.

The aim of our study is to present the particularities of a specific subset of gynecological cancer patients in Romania. We present a review of synchronous gynecological neoplasia (SGN) treated in the Bucharest Oncological Institute's surgery departments over a decade. Between 2012 and 2022, 7419 female patients with genital malignancies were treated. We identified 36 patients with invasive synchronous primary gynecological cancers (0.5%) and 12 cases with one primary gynecological and another primary invasive pelvic cancer (rectal/bladder). All recurrent, metastatic, or metachronous tumors detected were excluded. Demographic data, personal history, presenting symptoms, pathologic findings, staging, treatment, and evolution for each case were recorded. Usually, the most common SGN association is between ovarian and endometrial cancer of endometrioid differentiation (low-grade malignancies with very good prognosis). However, we noticed that, given the particularities of the Romanian medical system, the most frequent association is between cervical and endometrial, followed by cervical and ovarian cancers. Moreover, the cancer stage at diagnosis is more advanced. In countries with low HPV vaccination rate and low adherence to screening programs, SGNs can present as extremely advanced cases and require extensive surgery (such as pelvic exenterations) to achieve radicality. This multimodal treatment in advanced cases with high tumor burden determines a reduction in survival, time until progression, and quality of life.

A Retrospective Analysis Comparing VATS Cost Discrepancies and Outcomes in Primary Lung Cancer vs. Second Primary Lung Cancer Patients.

This study aimed to compare the outcomes and cost differences between primary lung cancer (PLC) and second primary lung cancer (SPLC) patients who underwent video-assisted thoracoscopic surgery (VATS). This was a retrospective analysis of 124 patients with lung cancer stages I, II, and III who underwent VATS between January 2018 and January 2023. The patients were divided into two groups based on their cancer status that was matched by age and gender: the PLC group (n = 62) and the SPLC group (n = 62). The results showed that there was no significant difference in the clinical characteristics between the 2 groups, except for the Charlson Comorbidity Index (CCI), with a score above 3 in 62.9% of PLC patients and 80.6% among SPLC patients (p = 0.028). Regarding the surgical outcomes, the operative time for the VATS intervention was significantly higher in the SPLC group, with a median of 300 min, compared with 260 min in the PLC group (p = 0.001), varying by the cancer staging as well. The average duration of hospitalization was significantly longer before and after surgery among patients with SPLC (6.1 days after surgery), compared with 4.2 days after surgery in the PLC group (0.006). Regarding the cost analysis, the total hospitalization cost was significantly higher in the SPLC group (15,400 RON vs. 12,800 RON; p = 0.007). Lastly, there was a significant difference in the survival probability between the two patient groups (log-rank p-value = 0.038). The 2-year survival was 41.9% among PLC patients and only 24.2% among those with SPLC. At the 5-year follow-up, there were only 1.6% survivors in the SPLC group, compared with 11.3% in the PLC group (p-value = 0.028). In conclusion, this study found that VATS is a safe and effective surgical approach for both PLC and SPLC patients. However, SPLC patients have a higher VATS operating time and require more healthcare resources than PLC patients, resulting in higher hospitalization costs. These findings suggest that careful pre-operative evaluation and individualized surgical planning are necessary to optimize the outcomes and cost-effectiveness of VATS for lung cancer patients. Nevertheless, the 5-year survival remains very low and concerning.

The Female Reproductive Tract Microbiome and Cancerogenesis: A Review Story of Bacteria, Hormones, and Disease.

The microbiota is the complex community of microorganisms that populate a particular environment in the human body, whereas the microbiome is defined by the entire habitat-microorganisms and their environment. The most abundant and, therefore, the most studied microbiome is that of the gastrointestinal tract. However, the microbiome of the female reproductive tract is an interesting research avenue, and this article explores its role in disease development. The vagina is the reproductive organ that hosts the largest number of bacteria, with a healthy profile represented mainly by Lactobacillus spp. On the other hand, the female upper reproductive tract (uterus, Fallopian tubes, ovaries) contains only a very small number of bacteria. Previously considered sterile, recent studies have shown the presence of a small microbiota here, but there are still debates on whether this is a physiologic or pathologic occurrence. Of particular note is that estrogen levels significantly influence the composition of the microbiota of the female reproductive tract. More and more studies show a link between the microbiome of the female reproductive tract and the development of gynecological cancers. This article reviews some of these findings.

Analysis of Efficacy-To-Safety Ratio of Angiogenesis-Inhibitors Based Therapies in Ovarian Cancer: A Systematic Review and Meta-Analysis.

(1) Background: Among new anti-angiogenesis agents being developed and ever-changing guidelines indications, the question of the benefits/safety ratio remains unclear. (2) Methods: We performed a systematic review combined with a meta-analysis of 23 randomized controlled trials (12,081 patients), evaluating overall survival (OS), progression free survival (PFS) and toxicity (grade ≥ 3 toxic effects, type, and number of all adverse effects. (3) Results: The analysis showed improvement of pooled-PFS (HR, 0.71; 95% CI, 0.64-0.78; I2 = 77%; p < 0.00001) in first-line (HR, 0.85; 95% CI, 0.78-0.93; p = 0.0003) or recurrent cancer (HR, 0.62; 95% CI, 0.56-0.70; p < 0.00001) and regardless of the type of anti-angiogenesis drug used (Vascular endothelial growth factor (VEGF) inhibitors, VEGF-receptors (VEGF-R) inhibitors or angiopoietin inhibitors). Improved OS was also observed (HR, 0.95; 95% CI, 0.90-0.99; p = 0.03). OS benefits were only observed in recurrent neoplasms, both platinum-sensitive and platinum-resistant neoplasms. Grade ≥ 3 adverse effects were increased across all trials. Anti-angiogenetic therapy increased the risk of hypertension, infection, thromboembolic/hemorrhagic events, and gastro-intestinal perforations but not the risk of wound-related issues, anemia or posterior leukoencephalopathy syndrome. (4) Conclusions: Although angiogenesis inhibitors improve PFS, there are little-to-no OS benefits. Given the high risk of severe adverse reactions, a careful selection of patients is required for obtaining the best results possible.

Allergy in Cancer Care: Antineoplastic Therapy-Induced Hypersensitivity Reactions.

As the backbone of oncological treatments, systemic chemotherapy is still one of the main pawns in cancer care, alone or in combination with newer targeted agents. All chemotherapy agents can be associated with a type of adverse event called an infusion reaction, which can be characterized as unpredictable, non-dose related, and unexplained by the cytotoxic profile of the drug. For some of these events, a certain immunological mechanism can be identified by blood or skin testing. In this case, we can speak of true hypersensitivity reactions that occur as a response to an antigen/allergen. The current work summarizes the main antineoplastic therapy agents and their susceptibility to induce hypersensitivity reactions and also includes a review of clinical presentation, diagnostic methods in hypersensitivity reactions, and perspectives to overcome these negative events in the treatment of patients suffering from various types of cancer.

Prognostic Role of Vascular Endothelial Growth Factor and Correlation with Oxidative Stress Markers in Locally Advanced and Metastatic Ovarian Cancer Patients.

BACKGROUND: Vascular endothelial growth factor (VEGF) plays an important role in tumor progression in ovarian cancer, but the complex mechanism and interaction with oxidative stress are not fully understood. METHODS: A prospective study included 52 patients with ovarian adenocarcinoma stage IIIA-IV. Serum VEGF and reactive oxygen species (ROS) such as malondialdehyde and ceruloplasmin were measured. RESULTS: VEGF levels were elevated (mean 1014.7 ± 165 pg/mL), especially in patients with macroscopic residual disease (1058 vs. 810 pg/mL, p = 0.0001). Median progression-free survival (PFS) and overall survival (OS) were 6 and 40 months in patients with a very high VEGF (over 1200 pg/mL), 11 and 48 months in patients with VEGF between 1000-1200 pg/mL, 18 and 84 months in patients with VEGF between 800-1000 pg/mL, and not reached in patients with normal VEGF. Increased VEGF values were associated with a 2.6-fold increased risk of disease progression (HR = 2.60, 95% CI 1.69-3.99), and a 1.4-fold increased risk of death (HR = 1.4, 95% CI 1.15-1.91, p = 0.002). Receiver operator characteristic (ROC) curves were used to validate VEGF as a prognostic factor and the area under the curve (AUC) was 0.814, p = 0.036 for PFS and 0.729, p = 0.043, for OS. There was a positive correlation between VEGF and malondialdehyde, Pearson coefficient of 0.35, p = 0.0001. CONCLUSIONS: VEGF and malondialdehyde are important prognostic markers in ovarian cancer, especially in macroscopic residual disease, and there is a positive correlation between angiogenesis and oxidative stress.

Oncologic Outcome after Pulmonary Metastasectomy as Part of Multidisciplinary Treatment in a Tertiary Oncological Center.

(1) Background: Pulmonary metastases are encountered in approximately one-third of patients with malignancies, especially from colorectal, lung, breast, and renal cancers, and sarcomas. Pulmonary metastasectomy is the ablative approach of choice, when possible, as part of the multidisciplinary effort to integrate and personalize the oncological treatment. (2) Methods: The study includes 58 consecutive cases of pulmonary metastasectomies, retrospectively analyzed, performed in 12 consecutive months, in which the pathology reports confirmed lung metastases. (3) Results: Most frequent pathological types of metastases were: 14 of colorectal cancer, 10 breast, 8 lung, and 8 sarcomas. At the time of primary cancer diagnosis, 14 patients (24.14%) were in the metastatic stage. The surgical approach was minimally invasive through uniportal VATS (Video-Assisted Thoracic Surgery) in 3/4 of cases (43 patients, 74%). Almost 20% of resections were typical (lobectomy, segmentectomy). Lymphadenectomy was associated in almost 1/2 of patients and lymph node metastases were found in 11.11% of cases. The mortality rate (intraoperative and 90 days postoperative) is zero. The OS after pulmonary metastasectomy is 87% at 18 months, and the estimated OS for cancer is 90% at 5 years. The worst outcome presents the patients with sarcomas and the best outcome-colorectal and lung cancer. The patients with 1 or 2 resected metastases presented 96% survival at 24 months. (4) Conclusions: After pulmonary metastasectomy, survival is favored by the small number of metastases resected (1 or 2), and by the dimension of metastases under 20.5 mm. The non-anatomic (wedge) type of lung resection may present a lower risk of death compared to lobectomy. No statistical significance on survival has the presence of lymphadenectomy, the laterality right/left lung, the upper/lower lobes. In the future, longer follow-up and prospective randomized trials are needed for drawing definitive conclusions.

The Bidirectional Relationship between Pulmonary Tuberculosis and Lung Cancer.

Lung cancer and pulmonary tuberculosis are two significant public health problems that continue to take millions of lives each year. They may have similar symptoms and, in some cases, are diagnosed simultaneously or may have a causal relationship. In tuberculosis disease, the chronic inflammation, different produced molecules, genomic changes, and fibrosis are believed to be important factors that may promote carcinogenesis. As a reverse reaction, the development of carcinogenesis and the treatment may induce the reactivation of latent tuberculosis infection. Moreover, the recently used checkpoint inhibitors are a debatable subject since they help treat lung cancer but may lead to the reactivation of pulmonary tuberculosis and checkpoint-induced pneumonitis. Pulmonary rehabilitation is an effective intervention in post-tuberculosis patients and lung cancer patients and should be recommended to improve outcomes in these pathologies.

Malignant Extramucosal Esophageal Tumor - Yolk Sac Tumor - Case Report.

Malignant extramucosal esophageal tumors are rare. We publish a case of an extramucosal esophageal tumor which turned out to be a yolk sac tumor. This type of tumor is extremely rare. We present the initial and also late management of this case (from the diagnostic to the management of the late complications). The patient was admitted for dysphagia. Contrast thoraco-abdominal CT scan revealed an important retrocardiac mass; echoendoscopy with biopsy confirmed one malignant extra-mucosal esophageal tumor. We performed an esophagectomy through triple approaches (McKeown) â?" right thoracotomy, laparotomy, and left cervicotomy for anastomosis. The pathological report raised the suspicion of a mediastinal tumor with germ cells or a poorly differentiated carcinoma. The immunohistochemistry tests confirmed a yolk sac tumor. The patient was referred to the oncologist and was treated with etoposide and cisplatin chemotherapy. Subsequently, the patient developed respiratory failure secondary to giant hiatal hernia which was surgically treated via laparoscopy.

Minimally Invasive Thoracic Surgery - Video Assisted Thoracic Surgery: Technique and Indications.

Video-Assisted Thoracic Surgery (VATS) is already practised worldwide, in almost every condition addressed by open thoracic surgery. As part of minimally invasive thoracic surgery (MITS), VATS offers to patients and to healthcare providers excellent results and great satisfactions. Learning and performing VATS use different pathways in trainees and in experienced surgeons. This article presents VATS in its essence: classification, indications, contraindications, instruments and tools, incisions and access, troubleshooting, learning curve and training. We wish that the information helps our colleagues, both trainees and experienced thoracic surgeons, to start and continue performing VATS as standard care in thoracic surgery.

The Importance of Route Anatomic Variants of the Common Hepatic Artery.

Introduction: Variants of vascularization in the celiac and upper mesenteric artery are described in the dedicated literature. The anatomy of this area is a subject of interest, considering the potential techniques and the risk of generating intraoperative incidents/accidents or complications. Material and method: We have conducted a unicentric retrospective study, in the Surgery Clinic No.1 of "Prof. Dr. Al. Trestioreanu" Institute of Oncology from Bucharest, on an 11-year interval of time, concerning the occurrence of this rare route-related anomaly of the common hepatic artery, incidence which is evaluated in the dedicated literature at about 0.1%. The study consisted of two components, namely the relevant medical records, on the one hand and focus-group discussions with the 19 surgeons of our department regarding their personal operating experiences, on the other hand. We have identified two cases where this route abnormality of the common hepatic artery, i.e. the retroportal route variant, has been encountered. These two cases are fully documented, including CT-scan and intraoperative images, and they are briefly presented hereinafter. Results: Anatomical variants of the celiac trunk represent an extremely researched topic, considering the major implications in hepato-pancreato-biliary surgery and liver transplantation. Variants of route or origin of the hepatic artery can be the cause of numerous incidents and accidents in hepato-pancreato-biliary oncology surgery, but also in that of trauma. Non-recognition of anatomical, preoperative or intraoperative variants can result in important vascular lesions, especially of the portal vein, which can greatly complicate the resection time. Conclusions: Route variants of the hepatic artery are particularly important in liver transplantation, hepato-pancreato-biliary or gastric oncology surgery, interventional radiology procedures, but also in trauma surgery, especially in case of supramesocolic abdominal penetrating lesions. It would be ideal for these variants to be recognized before surgery, so that the most appropriate surgical technique can be adopted.
