Chemotherapy in geriatric patients with poor performance status small cell lung cancer: Series from a tertiary care center
Geriatric age group patients with poor performance status and advanced stage cancer are often denied chemotherapy. In this series of cases, we demonstrated that systemic anti‐cancer therapy can be considered in these patients after a meticulous modification of the chemo‐protocol.
Longitudinal analysis of complete blood count parameters in advanced‐stage lung cancer patients
Background Metastatic lung cancer is a debilitating disease, but with the advances in immunotherapy, therapeutic options have vastly increased. Numerous complete blood count parameters (CBC) have been described as easily accessible biomarkers that might predict response to immunotherapy. However, to date, no comprehensive study has been performed on the longitudinal changes of these parameters during cancer progression. Methods The clinicopathological variables and CBC parameters of 986 advanced stage lung cancer patients were retrospectively analyzed. Blood tests were performed as part of the routine checkup and the results were recorded at the time of the diagnosis of the primary tumor, the diagnosis of brain or bone metastases, and also during the last available follow‐up. Results In the experimental subcohort, 352 and 466 patients were diagnosed with brain and bone metastases, respectively. The control group consisted of 168 patients without clinically detectable or other distant organ metastases. In our longitudinal analyses, we found significantly decreasing absolute lymphocyte count (ALC: P < 0.001), and significantly increasing absolute neutrophil count (ANC: P < 0.001) levels in all patient subgroups, irrespective of histopathological type and metastatic site. Interestingly, patients with brain metastases had significantly descending‐ascending platelet count (PLT) trendlines (P < 0.001), while the bone metastatic subgroup exhibited significantly ascending‐descending trendlines (P = 0.043). Conclusions Significantly decreasing ALC, significantly increasing ANC and fluctuating PLT levels may be found in brain and bone metastatic lung cancer patients during disease progression. Our findings might contribute to improve personalized healthcare in this devastating malignancy. Key points Significant findings of the study Significantly decreasing ALC, and significantly increasing ANC levels can be found in advanced‐stage lung cancer patients during disease progression Patients with brain metastases have descending‐ascending PLT trendlines, while patients with bone metastases exhibit ascending‐descending trendlines during disease progression What this study adds The descending values for ALC, and the ascending mean values for PLT and ANC, might be suggestive of poor response to second‐ or third‐line immunotherapy in advanced‐stage lung cancer patients. The current study might help to improve patient selection and treatment strategies for brain and/or bone metastatic lung cancer patients.

Natural Products for the Management of Castration-Resistant Prostate Cancer: Special Focus on Nanoparticles Based Studies
Prostate cancer is the most common type of cancer among men and the second most frequent cause of cancer-related mortality around the world. The progression of advanced prostate cancer to castration-resistant prostate cancer (CRPC) plays a major role in disease-associated morbidity and mortality, posing a significant therapeutic challenge. Resistance has been associated with the activation of androgen receptors via several mechanisms, including alternative dehydroepiandrosterone biosynthetic pathways, other androgen receptor activator molecules, oncogenes, and carcinogenic signaling pathways. Tumor microenvironment plays a critical role not only in the cancer progression but also in the drug resistance. Numerous natural products have shown major potential against particular or multiple resistance pathways as shown by in vitro and in vivo studies. However, their efficacy in clinical trials has been undermined by their unfavorable pharmacological properties (hydrophobic molecules, instability, low pharmacokinetic profile, poor water solubility, and high excretion rate). Nanoparticle formulations can provide a way out of the stalemate, employing targeted drug delivery, improved pharmacokinetic drug profile, and transportation of diagnostic and therapeutic agents via otherwise impermeable biological barriers. This review compiles the available evidence regarding the use of natural products for the management of CRPC with a focus on nanoparticle formulations. PubMed and Google Scholar search engines were used for preclinical studies, while ClinicalTrials.gov and PubMed were searched for clinical studies. The results of our study suggest the efficacy of natural compounds such as curcumin, resveratrol, apigenin, quercetin, fisetin, luteolin, kaempferol, genistein, berberine, ursolic acid, eugenol, gingerol, and ellagic acid against several mechanisms leading to castration resistance in preclinical studies, but fail to set the disease under control in clinical studies. Nanoparticle formulations of curcumin and quercetin seem to increase their potential in clinical settings. Using nanoparticles based on betulinic acid, capsaicin, sintokamide A, niphatenones A and B, as well as atraric acid seems promising but needs to be verified with preclinical and clinical studies.
Assessing the Impact of Exercise on Quality of Life in Advanced-Stage Cancer Patients: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials
Background/Objectives This systematic review and network meta-analysis aimed to determine the most effective therapeutic exercise modality for improving quality of life (QoL) in patients with advanced-stage cancer. Specifically, the study compared the effects of aerobic training, strength training, and combined aerobic and strength training on QoL outcomes. Methods A systematic literature search was conducted in PubMed, Embase, Cochrane Reviews, and the Cochrane Central Register of Controlled Trials up to 24 February 2023. The review adhered to PRISMA guidelines. Included studies were randomized controlled trials (RCTs) involving adult patients with advanced-stage cancers (e.g., pancreatic, colorectal, lung, breast, prostate, gastrointestinal, gynecological, hematological, head and neck, melanoma, or cancers with bone metastases). The primary outcome was post-intervention QoL, while the secondary outcome assessed was the dropout rate across exercise modalities. Results Aerobic training demonstrated the greatest improvement in QoL with a standardized mean difference (SMD) of 0.30 (95% CI: 0.00 to 0.61), followed by strength training (SMD = 0.13; 95% CI: −0.41 to 0.66) and combined training (SMD = 0.07; 95% CI: −0.11 to 0.24). However, none of the interventions showed statistically significant superiority. Dropout rates were comparable across all exercise modalities and control groups, suggesting strong adherence and feasibility of these interventions in advanced cancer populations. Conclusions While all exercise modalities were associated with improved QoL in patients with advanced-stage cancer, no single intervention emerged as significantly superior. Aerobic exercise may offer a slight advantage, although this effect was not statistically significant. These results highlight the importance of individualized exercise prescriptions based on patient preference, functional status, and treatment context. Further research is warranted to identify patient subgroups that may benefit most from specific exercise interventions and to explore QoL subdomains such as fatigue, emotional well-being, and physical functioning.
Advanced-stage breast cancer diagnosis and its determinants in Ethiopia: a systematic review and meta-analysis
Introduction Worldwide, breast cancer is the primary cause of illness and death. Unless early detected and treated breast cancer is a life-threatening tumor. Advanced-stage presentation is greatly linked with short survival time and increased mortality rates. In Ethiopia nationally summarized evidence on the level of advanced-stage breast cancer diagnosis is scarce. Therefore, this systematic review and meta-analysis aimed to determine the pooled prevalence of advanced-stage breast cancer diagnosis and its determinants in Ethiopia. Method By following PRISMA guidelines, a systematic review and meta-analysis were carried out. To include relevant publications, a broad literature search was conducted in the African Online Journal, PubMed, Google Scholar, and Embase which are published until last search date; June 15, 2023. To prevent further duplication this review was registered in PROSPERO database with ID no of CRD42023435096. To determine the pooled prevalence, a weighted inverse variance random effect model was applied. I 2 statistics and the Cochrane Q-test were computed to determine heterogeneity. To evaluate publication bias, a funnel plot, and Egger’s regression test were used. Result A total of 924 articles were sought and finally 20 articles were included in this review. The pooled prevalence of advanced-stage breast cancer diagnosis in Ethiopia was 72.56% (95%CI; 68.46-76.65%). Use of traditional medicine as first choice (AOR = 1.32, 95% CI: (1.13–1.55)), delay of > 3 months in seeking care (AOR = 1.24, 95% CI: (1.09–1.41)), diagnosis or health system delay of > 2 months (AOR = 1.27, 95% CI: (1.11–1.46)), rural residence (AOR = 2.04, 95% CI: (1.42 − 2.92)), and chief complaint of a painless breast lump (AOR = 2.67, 95% CI: (1.76–4.06)) were significantly associated to advanced-stage diagnosis. Conclusion In Ethiopia, more than two-thirds of breast cancer cases are diagnosed at an advanced stage. Use of traditional medicine before diagnostic confirmation, delay in seeking care, health system delay, rural residence, and chief complaint of painless breast lump were positively associated with an advanced-stage diagnosis. Policymakers and program designers give great focus to those delays so as to seek and access modern diagnosis and treatment as early as possible specifically focusing on those who are rurally residing.
Palliative care use and utilization determinants among patients treated for advanced stage lung cancer care in the community and academic medical setting
Purpose Despite clinical guidelines, palliative care is underutilized during advanced stage lung cancer treatment. To inform interventions to increase its use, patient-level barriers and facilitators (i.e., determinants) need to be characterized, especially among patients living in rural areas or those receiving treatment outside academic medical centers. Methods Between 2020 and 2021, advanced stage lung cancer patients ( n  = 77; 62% rural; 58% receiving care in the community) completed a one-time survey assessing palliative care use and its determinants. Univariate and bivariate analyses described palliative care use and determinants and compared scores by patient demographic (e.g., rural vs. urban) and treatment setting (e.g., community vs. academic medical center) factors. Results Roughly half said they had never met with a palliative care doctor (49.4%) or nurse (58.4%) as part of cancer care. Only 18% said they knew what palliative care was and could explain it; 17% thought it was the same as hospice. After palliative care was distinguished from hospice, the most frequently cited reasons patients stated they would not seek palliative care were uncertainty about what it would offer (65%), concerns about insurance coverage (63%), difficulty attending multiple appointments (60%), and lack of discussion with an oncologist (59%). The most common reasons patients stated they would seek palliative care were a desire to control pain (62%), oncologist recommendation (58%), and coping support for family and friends (55%). Conclusion Interventions should address knowledge and misconceptions, assess care needs, and facilitate communication between patients and oncologists about palliative care.
A frontier in oncology: managing stage IVB primary ovarian leiomyosarcoma with gallbladder metastasis: a case report and review of literature
Background Primary ovarian leiomyosarcoma is an exceedingly rare and aggressive tumor, accounting for less than 0.1% of ovarian malignancies. Owing to its nonspecific clinical presentation, primary ovarian leiomyosarcoma is often diagnosed at an advanced stage. To date, metastatic spread to the gallbladder has not been documented. Case presentation We present the first reported case of gallbladder metastasis arising from stage IVB primary ovarian leiomyosarcoma. A 55-year-old Iranian woman initially presented with a large ovarian mass and bilateral pulmonary metastases. She underwent radical surgical management—including total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic lymphadenectomy—followed by adjuvant chemotherapy with ifosfamide and doxorubicin. Owing to persistent pulmonary lesions, her regimen was switched to gemcitabine–docetaxel, which led to a partial response. During follow-up, imaging unexpectedly revealed gallbladder lesions, which were confirmed as metastatic primary ovarian leiomyosarcoma via laparoscopic cholecystectomy and histopathological analysis. Despite further systemic therapies, including sunitinib and a return to gemcitabine–docetaxel, the disease progressed with additional metastases to the liver, spine, and pancreas. The patient died 49 months after the initial surgery. Conclusion This case highlights an unprecedented metastatic pattern in primary ovarian leiomyosarcoma and suggests that individualized, multidisciplinary care may offer meaningful benefit in advanced disease. Given the rarity of primary ovarian leiomyosarcoma, cautious interpretation is warranted, and standardized treatment guidelines remain urgently needed. Vigilant long-term follow-up is crucial for detecting atypical disease progression.
Effect of MDMA-assisted therapy on mood and anxiety symptoms in advanced-stage cancer (EMMAC): study protocol for a double-blind, randomised controlled trial
Background Symptoms of anxiety and depression are common in patients with terminal illness and multiple challenges exist with timely and effective care in this population. Several centres have reported that one dose of the serotonergic psychedelic psilocybin, combined with therapeutic support, improves these symptoms for up to 6 months in this patient group. Drawing upon related therapeutic mechanisms, 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy may have the potential to achieve similar, positive mental health outcomes in this group. Preliminary evidence also supports the tolerability of MDMA-assisted therapy for anxiety and depression in advanced-stage cancer. Methods Up to 32 participants with advanced-stage cancer and associated depression and anxiety will be randomised in a 1:1 ratio into one of two blinded parallel treatment arms. The intervention group will receive 120 mg (+ 60 mg optional supplemental dose) MDMA-assisted therapy. The psychoactive control group will receive 20 mg oral (+ 10 mg optional supplemental dose) methylphenidate-assisted therapy. For each medication-assisted therapy session, participants will undergo two 90-min therapeutic support sessions in the week preceding, and one 90-min support session the day after the experimental session. A battery of measures (mood, anxiety, quality of life, mystical experience, spiritual wellbeing, attitudes towards death, personality traits, holistic health and wellbeing, connectedness, demoralisation, expectations, qualitative data and safety measures) will be assessed at baseline and through to the end of the protocol. Participants will be followed up until either 12 months post-randomisation or death, whichever occurs first. Discussion This study will examine the effect of MDMA-assisted therapy on symptoms of anxiety and depression in advanced-stage cancer. Potential therapeutic implications include establishing the safety and effectiveness of a novel treatment that may relieve mental suffering in patients with life-threatening illness.

Glucose-functionalized gold nanoparticles for effective photothermal therapy in lung cancer
Lung cancer remains the leading cause of cancer-related mortality worldwide, largely due to late-stage diagnoses that severely limit therapeutic interventions. In this context, nanoparticle-mediated photothermal therapy (PTT) has emerged as a promising and minimally toxic modality for solid tumors. We synthesized gold nanoparticles (AuNPs) with three distinct morphologies—spheres, rods, and stars—and functionalized them with polyethylene glycol (AuNPs-PEG) or polyethylene glycol conjugated with 2-deoxy-D-glucose (AuNPs-Gluc). In vitro analyses using human (A549, H1299) and murine (LLC) lung carcinoma cell lines demonstrated that PEGylation significantly attenuated AuNP-associated cytotoxicity, while glucose functionalization further enhanced biocompatibility. Inductively coupled plasma mass spectrometry quantification confirmed superior cellular uptake of AuNPs-Gluc compared to AuNPs-PEG ( p  < 0.05). Subsequent irradiation with a 980 nm diode laser (1 W) induced robust thermal damage and apoptotic cell death selectively in cancer cells treated with AuNPs-Gluc, sparing non-tumoral cells. Among the morphologies tested, star-shaped AuNPs exhibited the highest photothermal efficiency. In vivo experiments further substantiated the therapeutic potential, as combined administration of AuNPs-Gluc and laser irradiation significantly suppressed tumor growth ( p  < 0.01). Collectively, these findings highlight the utility of glucose-functionalized AuNPs as effective vectors for targeted PTT in lung cancer, supporting their translational relevance for future clinical applications in advanced-stage disease.
Abbreviated dignity therapy for adults with advanced-stage cancer and their family caregivers: Qualitative analysis of a pilot study
Dignity therapy (DT) is designed to address psychological and existential challenges that terminally ill individuals face. DT guides patients in developing a written legacy project in which they record and share important memories and messages with those they will leave behind. DT has been demonstrated to ease existential concerns for adults with advanced-stage cancer; however, lack of institutional resources limits wide implementation of DT in clinical practice. This study explores qualitative outcomes of an abbreviated, less resource-intensive version of DT among participants with advanced-stage cancer and their legacy project recipients. Qualitative methods were used to analyze postintervention interviews with 11 participants and their legacy recipients as well as the created legacy projects. Direct content analysis was used to assess feedback from the interviews about benefits, barriers, and recommendations regarding abbreviated DT. The legacy projects were coded for expression of core values.ResultFindings suggest that abbreviated DT effectively promotes (1) self-expression, (2) connection with loved ones, (3) sense of purpose, and (4) continuity of self. Participants observed that leading the development of their legacy projects promoted independent reflection, autonomy, and opportunities for family interaction when reviewing and discussing the projects. Consistent with traditional DT, participants expressed \"family\" as the most common core value in their legacy projects. Expression of \"autonomy\" was also a notable finding.Significance of resultsAbbreviated DT reduces resource barriers to conducting traditional DT while promoting similar benefits for participants and recipients, making it a promising adaptation warranting further research. The importance that patients place on family and autonomy should be honored as much as possible by those caring for adults with advanced-stage cancer.
