Multimodal Treatment Approach Research Articles

Low-dose intravitreal injection of 4 mg preservative-free gentamicin and superficial lamellar keratectomy combined with modified Gundersen grafts to control chronic heterochromic iridocyclitis and secondary keratitis in horses.

To describe a combined treatment approach for heterochromic iridocyclitis and secondary keratitis (HIK) in horses. A total of 15 horses (16 eyes). Sixteen eyes from 15 horses (mean age 14.1 years, range 6-26 years) received low-dose (4 mg) intravitreal preservative-free gentamicin injection (IVGI) and modified Gundersen grafts with standing sedation and local anesthesia following a clinical diagnosis of HIK. Additional therapies of suprachoroidal triamcinolone (8 mg) injection, episcleral bromfenac implants, and suprachoroidal cyclosporine implants were performed in individual cases. Leptospira titers were also reported when available. The most frequent ophthalmic findings were pigmented keratic precipitates (n = 15/16 eyes, 94%), corneal edema (n = 14/16 eyes, 88%), and pigmented cells suspended in the anterior chamber (n = 7/16 eyes, 44%). Postoperative treatment generally consisted of topical and systemic NSAIDs, topical antibiotics, and a topical mydriatic agent. Complications included persistent corneal edema (7/16, 44%), corneal ulceration (6/16, 38%), graft failure requiring revision (2/16, 13%), stromal abscess (1/16, 6%), surgery site infection (1/16, 6%), and suspected retinal degeneration following IVGI (1/16, 6%). One case was enucleated 6 months after treatment (1/16, 6%). Of the 12 eyes with at least 3 months of post-treatment follow-up, 10 were comfortable and visual with static or improved symptoms of HIK. This multimodal treatment approach aims to address both the anterior uveitis and endothelial decompensation frequently seen in horses with HIK. The surgery can be performed under standing sedation. Continued evaluation and long-term follow-up is necessary in all horses with HIK.

Chronic Thromboembolic Pulmonary Hypertension

Abstract: While the majority of patients have complete resolution of their acute pulmonary embolism (PE) after an adequate course of anticoagulation, some patients remain symptomatic with evidence of chronic PE. Chronic Thromboembolic Pulmonary Hypertension (CTEPH) and Chronic Thromboembolic Pulmonary Disease (CTEPD) are terms that describe symptomatic patients with chronic thromboembolic occlusions of the pulmonary arteries with or without pulmonary hypertension, respectively. Here, we review the definitions, epidemiology, pathobiology, diagnosis and management of CTEPH. The chronic PE in CTEPH is essentially a scar in the pulmonary vasculature and is accompanied by a pulmonary arteriolar vasculopathy. Ventilation-perfusion scanning is the most sensitive screening test for CTEPH, and diagnosis must be confirmed by right heart catheterization (RHC). Treatment decisions require a multidisciplinary team and guidance from additional imaging, usually CT or pulmonary angiography. While pulmonary endarterectomy (PEA) to remove the chronic PE surgically is still the first-line treatment for appropriate candidates, there is an expanding role for balloon pulmonary angioplasty (BPA) and medical treatment, as well as multimodality treatment approaches that incorporate all of those options. New imaging modalities and treatment strategies hold the promise to improve our care and management of CTEPH patients in the future.

Searching For Ideal Definite Treatment of Sinonasal Squamous Cell Carcinoma with Orbit Invasions.

Sinonasal squamous cell carcinoma (SqCC) often invades the orbit. Treatment of sinonasal cancer invading orbit can vary depending on the medical center and the extent of the invasion. The definitive treatment strategy, whether it involves preserving the orbit or not, varies on a case-by-case basis and leads to different outcomes. Currently, a multimodal treatment approach, which includes surgery, chemotherapy (CTx), radiotherapy (RT), or concurrent chemoradiotherapy (CCRT), is frequently employed for sinonasal cancers. This study aims to evaluate the prognosis of sinonasal SqCC with orbit invasion in various perspectives. We conducted a retrospective review of patients with primary sinonasal SqCC invading the orbit who were treated at between 2009 and 2018. We examined factors such as the extent of tumor, orbit invasion, treatment strategies, recurrence rates, and survival rates. Overall survival (OS) and disease-free survival (DFS) rates did not significantly differ based on the grade of orbit invasion. When tumor resection with orbit preservation was performed as definitive treatment, DFS was significantly longer compared to cases where surgery was not the definitive treatment (RT, CCRT). There was no significant difference in DFS between those who underwent orbit exenteration and those who underwent tumor resection with orbit preservation as the definitive treatment. Tumor resection with orbit preservation as the definitive treatment appears to be the preferred approach, leading to prolonged DFS while ensuring survival in cases of SqCC with orbit invasion.

Experiences of patients with endometriosis with a digital health application: a qualitative analysis.

Endometriosis is a frequent disease in women of reproductive age in which the endometrium occurs outside the uterine cavity. Multimodal treatment approaches are necessary due to loss of quality of life and the chronic nature of the disease. Digital health applications (DiGa) are becoming increasingly important. This research project investigates how a healthcare app can influence the subjective experience of illness in patients with endometriosis. Empiric data were collected through semi-structured interviews. Data analysis was carried out using qualitative focussed interview analysis. Reliability was ensured by joint interdisciplinary and interprofessional evaluation of the interviews by experts and those affected. Ten patients with endometriosis and the prescribed healthcare app Endo-App© were examined. Categories were defined from the superordinate categories "Factors influencing the experience of illness" and "Evaluation of the app". The app provided reliable information, promoted self-efficacy through exercises and strengthened the perception of the individuality of the illness. It helped to minimise nocebo effects from internet research and enabled a positive change of perspective. Patients criticised the time required for data input and had data protection concerns. The educational elements were often seen as redundant. Some patients only used the app briefly, or not at all. Once a DiGa has been prescribed, it may be useful to explain its use on an outpatient basis and validate regular use. Blind re-prescribing of DiGas should be avoided. Younger patients with a recent diagnosis or patients following rehabilitation may benefit more from prescribing.

Insights into Dyspareunia: From Diagnosis to Multimodal Treatment Approaches

Introduction and Purpose: Dyspareunia is a sexual disorder associated with pain in women. It refers to pain related to sexual intercourse. Pain can occur during penetration attempts, during penetration, during intercourse, and shortly after penetration. Studies conducted in the United States indicate that the problem of pain during intercourse affects as much as 10-20% of women. [1] In Poland, this number is estimated to be around 13%.[1] The aim of this review is to delve into the existing literature on the diagnosis of dyspareunia in women and to raise awareness of its extensive nature, emphasizing an interdisciplinary approach to patient care. A Brief Description of the State of Knowledge: The etiology of dyspareunia is multifactorial and may arise from pathological changes in the vulva and vagina, inflammatory changes, contact irritations, as well as vulvar conditions such as lichen sclerosus and flat. [3] Additionally, hormonal changes, pelvic floor injuries, postpartum gynecological procedures also play a significant role. Psychological factors such as trauma, anxiety, and depression are also important [4]. Conclusions: Dyspareunia is a condition that significantly affects the quality of life of women in various ways, thus necessitating effective therapeutic approaches. Collaboration among diverse specialists such as gynecologists, sexologists, psychotherapists, psychiatrists, and physiotherapists is crucial. Further research focusing on multimodal strategies is needed to effectively tailor treatments and mitigate the systemic effects of chronic pain.

Dissecting the Natural Patterns of Progression and Senescence in Pediatric Low-Grade Glioma: From Cellular Mechanisms to Clinical Implications.

Pediatric low-grade gliomas (PLGGs) comprise a heterogeneous set of low-grade glial and glioneuronal tumors, collectively representing the most frequent CNS tumors of childhood and adolescence. Despite excellent overall survival rates, the chronic nature of the disease bears a high risk of long-term disease- and therapy-related morbidity in affected patients. Recent in-depth molecular profiling and studies of the genetic landscape of PLGGs led to the discovery of the paramount role of frequent upregulation of RAS/MAPK and mTOR signaling in tumorigenesis and progression of these tumors. Beyond, the subsequent unveiling of RAS/MAPK-driven oncogene-induced senescence in these tumors may shape the understanding of the molecular mechanisms determining the versatile progression patterns of PLGGs, potentially providing a promising target for novel therapies. Recent in vitro and in vivo studies moreover indicate a strong dependence of PLGG formation and growth on the tumor microenvironment. In this work, we provide an overview of the current understanding of the multilayered cellular mechanisms and clinical factors determining the natural progression patterns and the characteristic biological behavior of these tumors, aiming to provide a foundation for advanced stratification for the management of these tumors within a multimodal treatment approach.

PARP Inhibitors in Brain Metastases from Epithelial Ovarian Cancer through a Multimodal Patient Journey: Case Reports and Literature Review.

Epithelial ovarian cancer (EOC) is the deadliest gynecological malignancy worldwide. Brain metastasis (BM) is quite an uncommon presentation. However, the likelihood of central nervous system (CNS) metastasization should be considered in the context of disseminated disease. The therapeutic management of BMs is an unmet clinical need, to date. We identified, across different cancer centers, six cases of both BRCA wild-type and BRCA-mutated EOCs spreading to the CNS. They presented either with a single brain lesion or with multiple lesions and most of them had intracranial-only disease. All cases received Poly-ADP ribose polymerase inhibitor (PARPi) maintenance, as per clinical practice, for a long time within a multimodal treatment approach. We also provide an insight into the available body of work regarding the management of this intriguing disease setting, with a glimpse of future therapeutic challenges. Despite the lack of unanimous guidelines, multimodal care pathways should be encouraged for the optimal disease control of this unfortunate patient subset. Albeit not being directly investigated in BM patients, PARPi maintenance is deemed to have a valuable role in this setting. Prospective research, aimed to implement worthwhile strategies in the multimodal patient journey of BMs from EOC, is eagerly awaited.

Conservative Management of Occipital Neuralgia Supported by Physical Therapy: A Review of Available Research and Mechanistic Rationale to Guide Treatment.

Conservative management is consistently recommended as a first line intervention for occipital neuralgia (ON); however, there is limited clinical research regarding conservative intervention for ON. This lack of research may lead to underutilization or unwarranted variability in conservative treatment. This article provides mechanism-based guidance for conservative management of ON as a component of a multimodal treatment approach, and discusses the role of the physical therapist in the care team. It also highlights opportunities for further research to refine conservative management of this condition. Published research on conservative interventions specific to ON is limited to very low-quality evidence for the use of TENS. The contemporary shift toward precision pain management emphasizing treatment based on a patient's constellation of clinical features-a phenotype-rather than solely a diagnosis provides more personalized and specifically targeted pain treatment. This paradigm can guide treatment in cases where diagnosis-specific research is lacking and can be used to inform conservative treatment in this case. Various conservative interventions have demonstrated efficacy in treating many of the symptoms and accepted etiologies of ON. Conservative interventions provided by a physical therapist including exercise, manual therapy, posture and biomechanical training, TENS, patient education, and desensitization have mechanistic justification to treat symptoms and causes of ON. Physical therapists have adequate time and skill to provide such progressive and iterative interventions and should be included in a multimodal treatment plan for ON. Further research is required to determine appropriate dosing, sequencing, and progression of conservative treatments.

Prospective randomized multicenter phase III trial comparing perioperative chemotherapy (FLOT protocol) to neoadjuvant chemoradiation (CROSS protocol) in patients with adenocarcinoma of the esophagus (ESOPEC trial).

LBA1 Background: The most effective multimodal approach for treatment of resectable locally advanced esophageal adenocarcinoma (EAC) is under debate. A prior ranking question is if neoadjuvant chemoradiation therapy or perioperative chemotherapy is superior. ESOPEC (NCT02509286) is a multicenter prospective randomized trial comparing neoadjuvant CROSS (41.4Gy plus carboplatin/paclitaxel) followed by surgery versus perioperative FLOT (5-FU/ leucovorin/oxaliplatin/docetaxel) and surgery for the curative treatment of EAC. Methods: Patients with cT1 cN+ cM0 or cT2-4a cNany cM0 resectable EAC were eligible. The primary endpoint is overall survival (OS; 90% power; hazard ratio [HR] 0.645, 218 events needed; one sided significance level of 2.5%). Analysis is by intention-to-treat in all randomized patients. The effect of treatment on OS is estimated using Cox regression stratified by study site, and including N stage (N0, N+), and age as covariates. Results: Between Feb 2016 and Apr 2020, 438 patients from 25 sites in Germany were randomly assigned to two treatment groups (221 FLOT; 217 CROSS). Baseline characteristics (male sex 89.3%, median age 63 [range 30-86], cT3/4 80.5%; cN+ 79.7%) were well balanced between both arms. Neoadjuvant treatment was started in 403 patients (207 FLOT; 196 CROSS). Surgery was done in 371 patients (191 FLOT; 180 CROSS). R0 resection was achieved in 351 patients (180 FLOT; 171 CROSS). 90 days postsurgical mortality was 4.3% (3.2% FLOT; 5.6% CROSS). After a median follow up of 55 months, 218 patients had died (97 FLOT; 121 CROSS). Median OS was 66 (95% CI 36 – not estimable) months in the FLOT arm, and 37 (95% CI 28 – 43) months in the CROSS arm. The 3-year OS rates were 57.4% (95% CI 50.1 – 64.0%) for FLOT and 50.7% (95% CI 43.5 – 57.5%) for CROSS (HR 0.70, 95% CI 0.53-0.92, p=0.012). In 359 patients with available tumor regression status, pathological complete response was achieved in 35 (19.3%, 95%-CI 13.9 – 25.9%) in FLOT and in 24 (13.5%, 95%-CI 8.8 – 19.4%) in CROSS. Conclusions: Perioperative FLOT improves survival in resectable EAC compared to neoadjuvant CROSS. Funding: The trial was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), project number 264590883. Clinical trial information: NCT02509286 .

Formula diets for weight loss - chances and challenges

Formula diets, through the use of industrially manufactured meal replacement products, lead to effective and rapid weight reduction and improvement in obesity-associated comorbidities. The specific composition of these meal replacement products simplifies the adherence to calorie goals and ensures the supply of essential nutrients during significant energy restriction. Despite numerous potential applications, evidence from randomized controlled studies, and simplicity in practical implementation, challenges persist. Monotony and social restrictions complicate adherence and acceptance. The use of formula diets for sustainable weight loss requires integration into a multimodal treatment approach with the goal of long-term changes in eating and activity behaviour. This includes accompanying nutritional counselling, promotion of physical activity, evaluation of adjuvant pharmacological or interventional therapies, as well as psychological support. The development of new incretin-based anti-obesity medications has opened another application field for formula products. There is optimization potential in expanding the product range and combining it with digital applications to enhance acceptance and reach a larger patient group.

Intravitreal chemotherapy (IVC) in retinoblastoma: A study of clinical variables and ocular preservation outcomes.

10059 Background: Retinoblastoma, a primary intraocular malignancy, poses unique challenges in preserving life and vision. This retrospective study aims to analyze the impact of IVC in a population of retinoblastoma patients. The primary objective to avoid external radiotherapy, a recognized risk factor for second neoplasms, particularly in germline retinoblastoma cases. Methods: We conducted an analysis of retinoblastoma patients from 2011 to 2024. Clinical variables, including sex, age, laterality, intraocular retinoblastoma staging, and therapies employed, were prospectively documented. Results: The study included 59 patients (37 male; 22 female). Thirty-three percent of patients had unilateral tumors and an average age of 28 months at diagnosis, and 67% had bilateral tumors with an average age of 15 months. Sixty-one eyes were treated and classified at diagnosis as follow: 6 (9.8%) in groups A and B, 10(18%) in group C, 37(64%) in group D, 6(11%) in group E, and 2(3%) without initial information. IVC was administered as part of a multimodal treatment approach. A total of 203 cycles of IVC were performed, averaging 3.4 cycles per patient. Melphalan was used in 39% of cycles, followed by the combination of melphalan and topotecan in 35%, and topotecan alone in 26%. Seven of 61 (11.5%) were enucleated. Three of 61 eyes (4.9%) received radiotherapy. Control of vitreous seeds and vision preservation were achieved in 57/61 eyes (93%). No grade 3 or 4 adverse events occurred. Conclusions: IVC emerges as a crucial component in the management of retinoblastoma, offering a viable alternative to external radiotherapy. The analysis highlights the importance of this approach in preserving ocular integrity, thereby avoiding enucleation and reducing the risk of second neoplasms, particularly in germline retinoblastoma patients.

Application of artificial intelligence to hepatobiliary cancer clinical outcomes research

The rapid evolution of modern technology has made artificial intelligence (AI) an important emerging tool in healthcare. AI, which is a broad field of computer science, can be used to develop systems or machines equipped with the ability to tackle tasks that traditionally necessitate human intelligence. AI can be used to perform multifaceted tasks that involve the synthesis of large amounts of data with the generation of solutions, algorithms, and decision support tools. Various AI approaches, including machine learning (ML) and natural language processing (NLP), are increasingly being used to analyze vast healthcare datasets. In addition, visual AI has the potential to revolutionize surgery and the intraoperative experience for surgeons through augmented reality enhancing surgical navigation in real-time. Specific applications of AI in hepatobiliary tumors such as hepatocellular carcinoma and biliary tract cancer can improve patient diagnosis, prognostic risk stratification, as well as treatment allocation based on ML-based models. The integration of radiomics data and AI models can also improve clinical decision making. We herein review how AI may be of particular interest in the care of patients with complex cancers, such as hepatobiliary tumors, as these patients often require a multimodal treatment approach.

Reconstruction options for infection-related defects : Plastic surgery armamentarium

The occurrence of infections has always been feared in all surgical disciplines. Plastic reconstructive surgery faces the challenge of treating infection-related defects on apatient-specific basis, which requires amultidisciplinary treatment concept. Satisfactory treatment success can only be achieved through radical debridement for infection cleansing, optimization of the perfusion situation paired with targeted anti-infective treatment and, if necessary, with soft tissue reconstruction by plastic surgery. This article presents the current possibilities of plastic and reconstructive surgery with respect to the reconstruction of infection-related defects. Proven and reliable strategies are presented and supplemented by promising experimental approaches. Due to the often multilayered defect situation caused by infections, from the epidermis to cancellous bone, the entire armamentarium of plastic and reconstructive surgery is used for reconstruction. The early involvement of plastic surgery in the treatment of infections and the interdisciplinary and multimodal treatment approach have proven their worth in the treatment of complex infection situations.

Treatment strategies for recurrent rectal cancer

Multimodal treatment approaches with neoadjuvant radiotherapy and chemotherapy followed by oncological and total mesorectal excision (TME) have significantly reduced the recurrence rate even in locally advanced rectal cancer. Nevertheless, up to 10% of patients develop alocal relapse. Surgical R0 resection is the only chance of a cure in the treatment of locally recurrent rectal cancer (LRRC). Due to the altered anatomy and physiology of the true pelvis as aresult of the pretreatment and operations as well as the localization and extent of the recurrence, the treatment decision is individualized and remains achallenge for the interdisciplinary team. Even locally advanced tumors with involvement of adjacent structures can be treated in designated centers using multimodal treatment concepts with potentially curative intent.

Conversion therapy for advanced hepatocellular carcinoma in the era of precision medicine: Current status, challenges and opportunities.

Hepatocellular carcinoma (HCC), the most prevalent malignancy of the digestive tract, is characterized by a high mortality rate and poor prognosis, primarily due to its initial diagnosis at an advanced stage that precludes any surgical intervention. Recent advancements in systemic therapies have significantly improved oncological outcomes for intermediate and advanced-stage HCC, and the combination of locoregional and systemic therapies further facilitates tumor downstaging and increases the likelihood of surgical resectability for initially unresectable cases following conversion therapies. This shift toward high conversion rates with novel, multimodal treatment approaches has become a principal pathway for prolonged survival in patients with advanced HCC. However, the field of conversion therapy for HCC is marked by controversies, including the selection of potential surgical candidates, formulation of conversion therapy regimens, determination of optimal surgical timing, and application of adjuvant therapy post-surgery. Addressing these challenges and refining clinical protocols and research in HCC conversion therapy is essential for setting the groundwork for future advancements in treatment strategies and clinical research. This narrative review comprehensively summarizes the current strategies and clinical experiences in conversion therapy for advanced-stage HCC, emphasizing the unresolved issues and the path forward in the context of precision medicine. This work not only provides a comprehensive overview of the evolving landscape of treatment modalities for conversion therapy but also paves the way for future studies and innovations in this field.

Dysmenorrhea: a disabling pain.

Dysmenorrhea is a common menstrual condition in women of reproductive age, characterized by pelvic pain during the menstrual cycle. This article reviews the risk factors, clinic and diagnosis of primary dysmenorrhea to propose a multimodal treatment approach for this condition. Primary dysmenorrhea is pelvic pain associated with the menstrual period without underlying pelvic pathology. In contrast, secondary dysmenorrhea refers to pelvic pain that presents as a symptom of other gynecologic conditions. Diagnosis is based on detailed clinical history, physical and gynecological examination, and complementary tests may be performed in specific cases. Treatment of primary dysmenorrhea is multimodal and aims to relieve pain and improve the patient’s quality of life. Nonsteroidal anti-inflammatory drugs are the first line of treatment, although other therapeutic approaches can be employed.

The impact of tumor budding and single-cell invasion on survival in patients with stage III/IV locally advanced oral squamous cell carcinoma- results from a prospective cohort study.

Tumor budding (TB) refers to the presence of small clusters of tumor cells at the invasive front of a malignant tumor. Single tumor cell invasion (SCI) is an extreme variant of TB, in which individual loose tumor cells are present at the invasive front. Both TB and SCI are important histomorphologic risk factors postulated to indicate loss of cellular cohesion. In this study, we investigated the influence of TB and SCI on different survival outcomes in patients with locally advanced oral squamous cell carcinoma (OSCC). We included 129 patients with locally advanced OSCC (pT3-4) from a single-center, prospectively maintained cohort. We examined the association of TB and SCI with the presence of occult lymph node metastasis using a logistic regression model. Survival probabilities were estimated using the Kaplan-Meier method and cumulative incidence functions. The association of TB and SCI on overall survival (OS), oral cancer-specific survival (OCSS), and local recurrence-free survival (LRFS) was investigated using Cox's proportional hazards regression models. TB was detected in 98 (76%) of the tumors, while SCI was observed in 66 (51%) patients. There was a significant association between TB and the occurrence of occult lymph node metastasis (OR=3.33, CI: 1.21-10.0). On multivariate analysis, TB had no detectable impact on survival outcomes. However, SCI showed a higher risk for local recurrence (Hazards ratio (HR): 3.33, CI: 1.19 - 9.27). This study demonstrates that TB and SCI in locally advanced OSCC function as an independent risk factor for occult lymph node metastases, as well as local recurrences. Both histomorphologic risk factors could serve as an additional parameter for stratifying therapy and escalating multimodal treatment approaches.

Combination of calretinin, MALAT1, and GAS5 as a potential prognostic biomarker to predict disease progression in surgically treated mesothelioma patients

BackgroundThe role of cytoreductive surgery for epithelioid pleural mesothelioma within a multimodal treatment approach remains controversial. Carefully selected patients benefit from cytoreductive surgery and adjuvant chemotherapy, but there is no established biomarker to predict tumor recurrence or progression during the course of the disease. The aim of this study was to identify potential biomarkers to predict therapeutic response in terms of progression-free survival. MethodsBetween 03/2014 and 08/2022, preoperative blood samples were collected from 76 patients with epithelioid pleural mesothelioma who underwent cytoreductive surgery as part of a multimodal treatment approach. Identification of potential biomarkers was performed by determination of mesothelin and calretinin, as well as specific long non-coding RNAs and microRNAs. Receiver operating characteristic analysis, Kaplan-Meier survival analysis, and Cox regression were used to assess the association between biomarker concentrations and patient recurrence status and survival. ResultsMALAT1, GAS5, and calretinin showed statistically significant increased biomarker levels in patients with recurrence in contrast to recurrence-free patients after surgical treatment (p < 0.0001, p = 0.0190, and p = 0.0068, respectively). The combination of the three biomarkers resulted in a sensitivity of 68 % and a specificity of 89 %. ConclusionMALAT1, GAS5, and calretinin could be potential biomarkers for the prediction of tumor recurrence, improving the benefit from multimodal treatment including cytoreductive surgery.

Multimodal Treatment of Pleural Mesothelioma with Cytoreductive Surgery and Hyperthermic Intrathoracic Chemotherapy: Impact of Additive Chemotherapy.

Cytoreductive surgery (CRS) combined with hyperthermic intrathoracic chemoperfusion (HITOC) is a promising treatment strategy for pleural mesothelioma (PM). The aim of this study was to evaluate the impacts of this multimodal approach in combination with systemic treatment on disease-free survival (DFS) and overall survival (OS). In this retrospective multicenter study, clinical data from patients after CRS and HITOC for PM at four high-volume thoracic surgery departments in Germany were analyzed. A total of 260 patients with MPM (220 epithelioid, 40 non-epithelioid) underwent CRS and HITOC as part of a multimodal treatment approach. HITOC was administered with cisplatin alone (58.5%) or cisplatin and doxorubicin (41.5%). In addition, 52.1% of patients received neoadjuvant and/or adjuvant chemotherapy. The median follow-up was 48 months (IQR = 38 to 58 months). In-hospital mortality was 3.5%. Both the resection status (macroscopic complete vs. incomplete resection) and histologic subtype (epithelioid vs. non-epithelioid) had significant impacts on DFS and OS. In addition, adjuvant chemotherapy (neoadjuvant/adjuvant) significantly increased DFS (p = 0.003). CRS and HITOC within a multimodal treatment approach had positive impacts on the survival of patients with epithelioid PM after macroscopic complete resection. The addition of chemotherapy significantly prolonged the time to tumor recurrence or progression.
