Core Viewpoint - The article discusses the promising results of fecal microbiota transplantation (FMT) combined with immunotherapy in treating non-small cell lung cancer (NSCLC), melanoma, and metastatic renal cell carcinoma (mRCC), highlighting its potential to overcome resistance to PD-1 therapy and improve patient outcomes [2][3][4]. Group 1: FMT and Immunotherapy in NSCLC and Melanoma - The FMT-LUMINate trial demonstrated an objective response rate (ORR) of 80% (16/20) in NSCLC and 75% (15/20) in melanoma, achieving the primary endpoint [8]. - Safety assessments indicated no grade 3 or higher adverse events in the NSCLC cohort, while 65% of melanoma patients experienced grade 3 or higher adverse events [8]. - The study found that responders had a unique gut microbiome composition post-FMT, with significant reductions in specific bacterial species associated with non-responders [9]. Group 2: FMT in Metastatic Renal Cell Carcinoma - The PERFORM trial showed that 50% (10/20) of mRCC patients experienced grade 3 immune-related adverse events, with no severe FMT-related toxicities reported [11][14]. - The objective response rate was 50% (9/18), including 11% (2/18) achieving complete response, with most responders not experiencing severe immune-related adverse events [14]. - Improvements in gut microbiome diversity were linked to reduced toxicity and enhanced treatment response, while the presence of specific bacteria correlated with higher immune-related adverse events [15][16]. Group 3: FMT Combined with Pembrolizumab and Axitinib - The TACITO trial evaluated the efficacy of donor-derived FMT in mRCC patients receiving pembrolizumab and axitinib, with a primary endpoint of disease progression-free survival [18][21]. - Although the primary endpoint was not met, the donor FMT group showed a significantly longer median progression-free survival of 24.0 months compared to 9.0 months in the placebo group [22]. - The donor FMT group had an ORR of 52%, while the placebo group had 32%, indicating potential benefits of selective donor FMT in enhancing immunotherapy outcomes [22].

Core Viewpoint - The article discusses the case of a patient diagnosed with Birt-Hogg-Dubé (BHD) syndrome, highlighting the rapid recurrence of kidney cancer post-surgery and the importance of genetic testing for accurate diagnosis and management [1][2]. Group 1: BHD Syndrome Overview - BHD syndrome is an autosomal dominant genetic disorder caused by mutations in the FLCN gene, with a 50% inheritance probability from an affected parent [2]. - The estimated prevalence of BHD syndrome is approximately 1-2 per million, but actual numbers may be higher due to underdiagnosis of mild or asymptomatic cases [2]. Group 2: Clinical Manifestations - Skin manifestations include small, painless, skin-colored or light red papules on the face, often misdiagnosed as acne or age spots [3]. - Lung involvement is characterized by thin-walled cysts that can lead to spontaneous pneumothorax, commonly misdiagnosed in young, tall individuals [4]. - About one-third of BHD patients will develop kidney tumors, typically presenting bilaterally and multifocally, with an average onset age of 50 [5]. Group 3: Sarcomatoid Change - Sarcomatoid change is not a new cancer but a transformation of existing renal cancer, marked by rapid growth and increased aggressiveness [6]. - The occurrence of sarcomatoid change in the context of BHD syndrome is rare but significantly impacts clinical outcomes, leading to increased invasiveness and reduced survival [6]. Group 4: Treatment Adjustments - The initial treatment with axitinib and PD-1 inhibitors failed within six weeks, indicating a more aggressive tumor behavior [7]. - A multidisciplinary team (MDT) decided to switch to an alternative treatment regimen involving anlotinib combined with immunotherapy [8]. - After four months, the tumor size decreased from 12 cm to 5 cm, indicating a partial response to the new treatment plan [9]. Group 5: Diagnosis and Management of BHD - Early suspicion of BHD should arise in cases of early-onset or bilateral/multifocal kidney tumors, or when associated with spontaneous pneumothorax [10]. - Genetic testing for FLCN mutations can be performed through blood or saliva samples, with results available in about two weeks [11]. - Management strategies include annual MRI scans of the kidneys starting at age 20, regular chest CT scans, and monitoring skin lesions [12].
