Malignant Chest Wall Tumors: Complex Defects and Their Management-A Review of 181 Cases.

BACKGROUND: Chest wall tumors are a heterogeneous group of tumors that are managed by surgeons from diverse specialties. Due to their rarity, there is no consensus on their diagnosis and management. MATERIALS: This retrospective, descriptive analysis includes patients with malignant chest wall tumors undergoing chest wall resection. Tumors were classified as primary, secondary, and metastatic tumors. The analysis includes clinicopathological characteristics, resection-reconstruction profile, and relapse patterns. RESULTS: A total of 181 patients underwent chest wall resection between 1999 and 2020. In primary tumors (69%), the majority were soft tissue tumors (59%). In secondary tumors, the majority were from the breast (45%) and lung (42%). Twenty-five percent of patients received neoadjuvant chemotherapy, and 98% of patients underwent R0 resection. Soft tissue, skeletal + soft tissue, and extended resections were performed in 45%, 70%, and 28% of patients, respectively. The majority of patients (60%) underwent rib resections, and a median of 3.5 ribs were resected. The mean defect size was 24 cm2. Soft tissue reconstruction was performed in 40% of patients, mostly with latissimus dorsi flaps. Rigid reconstruction was performed in 57% of patients, and 18% underwent mesh-bone cement sandwich technique reconstruction. Adjuvant radiotherapy and chemotherapy were given to 29% and 39% of patients, respectively. CONCLUSIONS: This is one of the largest single-institutional experiences on malignant chest wall tumors. The results highlight varied tumor spectra and multimodality approaches for optimal functional and survival outcomes. In limited resource setting, surgery, including reconstructive expertise, is very crucial.

Improving Access to Early Palliative Care Delivery for Patients With an Advanced Thoracic Malignancy Through an Embedded Oncopalliative Clinic Model.

PURPOSE: Early integration of palliative care (PC) with standard oncology care is driving the development of innovative PC delivery models. METHODS: This was a single-institution retrospective study of outpatient PC before and after the opening of an embedded thoracic oncology-palliative clinic at The Ohio State University. Patients included in the preintervention (October 2017-July 2018) and postintervention (October 2018-July 2019) cohorts had a diagnosis of any non-small-cell lung cancer (stages I-IV) or small-cell lung cancer (limited or extensive stage) and were newly established in the thoracic medical oncology clinic during the study time periods. All patients in the preintervention cohort had access to outpatient PC through a freestanding clinic, while the postintervention cohort had access to both freestanding and embedded clinics. Using time-to-event analyses, we evaluated differences in time intervals from first medical oncology visit to PC referral and first PC visit between cohorts. RESULTS: The majority of patients in both cohorts had metastatic disease at diagnosis. In the postintervention cohort, 20.9% of patients were referred to outpatient PC compared with 9.2% in the preintervention cohort (P < .01). PC referrals for patients outside of Franklin and adjacent counties increased from 4.0% to 14.2% after opening the embedded clinic (P < .01). Completion percentages of PC referrals increased from 57.6% to 76.0% in the preintervention versus postintervention cohorts (P = .048). Median time from palliative referral order to first PC visit decreased from 29 to 20 days (P = .047). Similarly, median time from the first oncology visit to PC referral completion decreased from 103 to 41 days (P = .08). CONCLUSION: Implementation of an embedded PC model was associated with increased access to early PC among patients with thoracic malignancies.

Feasibility of an embedded palliative care clinic model for patients with an advanced thoracic malignancy.

PURPOSE: Early palliative care (PC) with standard oncology care has demonstrated improved patient outcomes, but multiple care delivery models are utilized. This study prospectively evaluated the feasibility of an embedded PC clinic model and collected patient-reported outcomes (PROs) and caregiver needs. METHODS: In this observational study of embedded outpatient PC for patients with advanced thoracic malignancies treated at The Ohio State University Thoracic Oncology clinic, patients received same-day coordinated oncology and palliative care visits at one clinic location. PC encounters included comprehensive symptom assessment and management, advanced care planning, and goals of care discussion. Multiple study assessments were utilized. We describe the feasibility of evaluating PROs and caregiver needs in an embedded PC model. RESULTS: Forty patients and 28 caregivers were enrolled. PROs were collected at baseline and follow-up visits. Over a 12-month follow-up, 36 patients discontinued study participation due to hospice enrollment, death, study withdrawal, or COVID restrictions. At baseline, 32 patients (80%) rated distress as moderate-severe with clinically significant depression (44%) and anxiety (36%). Survey completion rates significantly decreased over time: 3 months (24 eligible, 66% completed), 6 months (17 eligible; 41% completed), 9 months (9 eligible; 44% completed), and 12 months (4 eligible; 50% completed). CONCLUSION: We found that an embedded PC clinic was feasible, although there were challenges encountered in longitudinal collection of PROs due to high study attrition. Ongoing assessment and expansion of this embedded PC model will continue to identify strengths and challenges to improve patient and caregiver outcomes.

Safety of mRNA-COVID-19 Vaccines in Patients With Thoracic Cancers.

BACKGROUND: Pivotal trials of COVID-19 vaccines did not include cancer patients with questions remaining in this population. Particularly in patients with thoracic malignancies receiving anticancer treatments, the safety of these vaccines has so far been little investigated. METHODS: This is a prospective trial of patients with thoracic cancer receiving anticancer treatments and COVID-19 vaccines at the Division of Thoracic Oncology of European Institute of Oncology between February and September 2021. RESULTS: A total 207 patients affected by thoracic cancers (199 lung cancers and 8 mesotheliomas) had received Covid-19 vaccines (206 mRNA vaccines and 1 virus-vectored vaccine). The majority of patients had at least one comorbidity (76.3%). They were concomitantly treating with targeted therapy (TT) (45.9%), immunotherapy (IO) (22.7%), and chemotherapy (CT) (14%). A total of 64 AEs (15.6%) were observed after administration of Sars-Cov-2 vaccine. The majority of AEs were grade 1 [G1] (6.3%) and G2 (8.8%), only two events were G3 (0.5%). The median follow-up was 9 months (range 1-22 months), during this follow-up 21 patients (10.1%) had a positive nasal swab, most of the patients were asymptomatic (67%) and the symptomatic ones (33%) had mild symptoms and fewer complications and hospitalizations. CONCLUSIONS: COVID-19 m-RNA vaccines appear to be safe in the cohort of patients with thoracic malignances in active treatment, including those receiving immunotherapy. Considering the high morbidity and mortality associated with COVID-19 in patients with lung cancer receiving active treatments, our study supports the current vaccine prioritization, third and/or fourth dose, of all cancer patients with active treatment.

Extracorporeal Membrane Oxygenation for Patients With Thoracic Neoplasms: An Extracorporeal Life Support Organization (ELSO) Registry Analysis.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is used in the management of severe cardiopulmonary failure, but the indication in the oncologic population has not been clearly established. Among malignant neoplasms, thoracic neoplasms are unique in their potential direct impact on cardiopulmonary function. This study aimed to better define the role of ECMO for thoracic neoplasms. METHODS: The Extracorporeal Life Support Organization registry was queried for patients older than 18 years with an International Classification of Diseases code of thoracic neoplasm during the past 2 decades (2000-2019). Outcomes and clinical data including associated procedures were analyzed. RESULTS: There were 498 patients who met inclusion criteria. The neoplasms included 34 upper airway, 247 lung, 45 unspecified respiratory tract, 4 pleura, 19 heart, 40 mediastinum, 108 esophagus, and 1 unspecified; 198 patients survived to discharge (39.8%; "survival"). Upper airway neoplasms were associated with better survival (73.5%; P = .005), whereas lung neoplasms were associated with worse survival (30.0%; P < .001) compared with all adult ECMO runs. Of the 498 cases, 94 (18.9%) were started after thoracic or airway procedures. Favorable survival was associated with tracheal procedures (66.7% [n = 9]), whereas poor survival was seen with pneumonectomy (13.3% [n = 30]), any type of lung resection (23.7% [n = 76]), and esophageal procedures (21.4% [n = 14]). CONCLUSIONS: The outcome for ECMO among patients with a thoracic neoplasm is variable, depending on clinical factors including tumor subtype and type of associated procedure. Clinicians should continue to focus on individualized patient selection to achieve optimal results.

Immunotherapy in Thoracic Malignancies: New Treatment and New Hope.

Over these last two pandemic years, we have all experienced profound changes in how we practice, how we work, and how we live [...].

Impact of telemedicine adoption on accessibility and time to treatment in patients with thoracic malignancies during the COVID-19 pandemic.

BACKGROUND: To ensure safe delivery of oncologic care during the COVID-19 pandemic, telemedicine has been rapidly adopted. However, little data exist on the impact of telemedicine on quality and accessibility of oncologic care. This study assessed whether conducting an office visit for thoracic oncology patients via telemedicine affected time to treatment initiation and accessibility. METHODS: This was a retrospective cohort study of patients with thoracic malignancies seen by a multidisciplinary team during the first surge of COVID-19 cases in Philadelphia (March 1 to June 30, 2020). Patients with an index visit for a new phase of care, defined as a new diagnosis, local recurrence, or newly discovered metastatic disease, were included. RESULTS: 240 distinct patients with thoracic malignancies were seen: 132 patients (55.0%) were seen initially in-person vs 108 (45.0%) via telemedicine. The majority of visits were for a diagnosis of a new thoracic cancer (87.5%). Among newly diagnosed patients referred to the thoracic oncology team, the median time from referral to initial visit was significantly shorter amongst the patients seen via telemedicine vs. in-person (median 5.0 vs. 6.5 days, p < 0.001). Patients received surgery (32.5%), radiation (24.2%), or systemic therapy (30.4%). Time from initial visit to treatment initiation by modality did not differ by telemedicine vs in-person: surgery (22 vs 16 days, p = 0.47), radiation (27.5 vs 27.5 days, p = 0.86, systemic therapy (15 vs 13 days, p = 0.45). CONCLUSIONS: Rapid adoption of telemedicine allowed timely delivery of oncologic care during the initial surge of the COVID19 pandemic by a thoracic oncology multi-disciplinary clinic.

Clinical case of lung spindle cell carcinoma markedly responsive to pembrolizumab.

A 52-year-old man underwent pneumonectomy of the left lung for previously diagnosed primary spindle cell carcinoma (pT4aN1M0, stage III B) with programmed death-ligand 1 expression (tumor proportion score ≥95%) and without epidermal growth factor receptor gene mutation and anaplastic lymphoma kinase fusion gene. However, brain metastasis and chest wall tumor relapse occurred. Considering insufficient improvement with gamma knife treatment for brain metastasis and combination chemotherapy (paclitaxel, carboplatin, and bevacizumab), pembrolizumab monotherapy and palliative irradiation therapy for chest metastases were started after brain tumor volume reduction using craniotomy. Brain edema and chest wall metastases markedly improved following a pseudoprogression of the brain edema accompanied by a performance status decline; this effect continued until 11 cycles of pembrolizumab administration.

Impact of COVID-19 on the management of patients with thoracic cancers in a tertiary referral center.

INTRODUCTION: Severe acute respiratory syndrome coronavirus (SARS-CoV)-2 has spread worldwide in 2020 leading the World Health Organization to declare a pandemic. Patients with thoracic cancers have been reported at higher risk to develop severe disease, and die from COVID-19. In this setting, clinical practice recommendations for the management of patients were published. We report here how these guidelines were implemented in a routine practice setting. METHODS: We retrospectively collected the characteristics, treatment regimen and modification, as well as COVID-19 status and death for all patients with thoracic malignancies scheduled for an appointment at Institute Curie from March 23rd to April 17th 2020. RESULTS: A total of 339 patients were included. Treatment strategy was modified for a total of 110 (32 %) patients because of COVID-19; these modifications were in accordance with guidelines for 92 % of patients. The majority of dose modifications were related to immune checkpoint inhibitors, for which switch to flat dosing every 4-6 weeks was made. A total of 5 (1.5 %) patients were diagnosed with COVID-19 disease, 1 of whom died from disease complication. CONCLUSION: Our study provides a unique insight in the decision making for patients with thoracic malignancies in the setting of COVID-19 outbreak, showing how guidelines were implemented in the clinic, and what may be optimized in the clinical practice of thoracic oncology in the future.

Long-term survival of airway silicone stents in patients with central airway stenosis or obstruction due to thoracic malignancy.

OBJECTIVES: Silicone airway stents are used to manage central airway stenosis or obstruction, although their impact on long-term survival remains unknown in patients with central airway stenosis or obstruction due to thoracic malignancy. In this study, we retrospectively analyzed the impact of silicone stents on survival. METHODS: We retrospectively analyzed clinical data of 106 patients with central airway stenosis or obstruction due to thoracic malignancy treated by stenting at Toho University Omori Medical Center between 1998 and 2018. RESULTS: Patients treated with silicone stents had significantly higher survival rates than patients treated with metallic stents (p = 0.0173). Silicone stents patients also had significantly more additional treatments for thoracic malignancy after stenting than metallic stents patients (p = 0.0007). Notably, significantly more silicone stents patients underwent chemoradiotherapy or radiotherapy (p = 0.0268, p = 0.0300). During multivariate analyses, the additional treatment, including chemoradiotherapy or radiotherapy, was an independent optimal prognostic factor. CONCLUSIONS: Silicone stents patients had significantly higher survival rates than metallic stents patients. Although stenting for airway stenosis or obstruction due to thoracic malignancy may be mainly palliative, additional treatments after stenting should be considered to improve the prognoses of patients with airway stenosis or obstruction due to thoracic malignancy.

Older Patients Treated for Lung and Thoracic Cancers: Unplanned Hospitalizations and Overall Survival.

BACKGROUND: Lung cancer affects older adults and is the leading solid tumor in terms of death. A Comprehensive Geriatric Assessment (CGA) is recommended before cancer treatment to guide therapy management. PATIENTS AND METHODS: This study was conducted between September 2015 and January 2019. During this period of time, all consecutive older outpatients referred for a CGA before initiation of lung or thoracic tumor treatment were included. The objectives were to describe the impact of geriatric factors on unplanned hospitalizations and overall survival (OS). The study was approved by a local ethics committee. RESULTS: Overall, 228 patients were recruited. The median age was 78.7 ± 5 years. The majority (82%) of patients were diagnosed with non-small-cell lung cancer, and the most common (40.4%) treatment was systemic therapy. In multivariate analysis, factors associated with unplanned hospitalizations within the first 3 months were male gender (adjusted odds ratio [aOR], 3.3; 95% confidence interval [CI], 1.5-7.2), systemic therapy (aOR, 2.6; 95% CI, 1.1-6.2), and fall history (aOR, 3.6; 95% CI, 1.6-8.2). Factors associated with a decrease in OS in the multivariate Cox model analysis were male gender (hazard ratio [HR], 3.9; 95% CI, 2.1-7.3), stage IV (HR, 1.6; 95% CI, 1.0-2.6), G8 ≤ 14 (HR, 3.5; 95% CI, 1.1-11.4), systemic therapy (HR, 2.6; 95% CI, 1.2-5.5), Eastern Cooperative Oncology Group performance status ≥ 2 (HR, 2.0; 95% CI, 1.2-3.4), and impaired handgrip strength (HR, 1.6; 95% CI, 1.0-2.5). CONCLUSION: G8 score and handgrip strength are important to predict OS in older adults treated for thoracic tumors. In the CGA, fall history was associated with unplanned hospitalization.

Randomized phase II trial of S-1 plus cisplatin or docetaxel plus cisplatin with concurrent thoracic radiotherapy for inoperable stage III non-small cell lung cancer.

Cisplatin-based chemoradiotherapy is considered standard treatment for unresectable locally advanced non-small-cell lung cancer (LA-NSCLC). This study examined two regimens of chemotherapy in concurrent chemoradiation. Eligible patients with unresectable, radically irradible LA-NSCLC were randomized to either the SP (S-1 and cisplatin) or DP (docetaxel and cisplatin) arms with concurrent thoracic radiotherapy of 60 Gy, comprising 2 Gy per daily fraction. The primary endpoint was the overall survival (OS) rate at 2 years (the 2-year OS rate). From May 2011 to August 2014, 110 patients were enrolled. Of 106 eligible patients, the 2-year OS rates were 79% (95% CI: 66%-88%) and 69% (95% CI: 55%-80%) the SP and DP arms, respectively. The median progression-free survival was 11.6 months for the SP arm and 19.9 months for the DP arm, while the median survival time was 55.2 months for the SP arm and 50.8 months for the DP arm. Grade 3/4 leukopenia were more frequent in DP arm. The incidences of febrile neutropenia and pneumonitis tended to be higher in DP arm. There were no treatment-related deaths in either arm. The primary endpoint was met in both arms. The SP arm as a future reference regimen will be chosen due to fewer toxicities and better OS.
