The persistent failure of standard chemotherapy underscores the urgent need for innovative and targeted approaches in cancer treatment. Photodynamic therapy (PDT) has emerged as a promising photochemistry-based approach to address chemoresistance in cancer regimens. PDT not only induces cell death but also primes surviving cells, enhancing their susceptibility to subsequent therapies. This review explores the principles of PDT and discusses the concept of photodynamic priming (PDP), which augments the effectiveness of treatments like chemotherapy. Furthermore, the integration of nanotechnology for precise drug delivery at the right time and location and PDT optimization are examined. Ultimately, this study highlights the potential and limitations of PDT and PDP in cancer treatment paradigms, offering insights into future clinical applications.

PURPOSE: An international shortage of ranitidine led to adjustments in premedication regimens for paclitaxel-based chemotherapy in early October 2019. In this study, we implemented and evaluated an anti-allergic protocol without histamine-2 antagonists (H2As) and aimed to assess the risk of hypersensitivity reactions (HSRs) to the different premedication regimens used. METHODS: We conducted a single-center observational retrospective study of paclitaxel administrations (7173 administrations in 831 patients). Between January 2019 and December 2020, all allergies reported were recorded. A mixed logistic regression model was implemented to predict the risk of allergy at each injection and to account for repeated administration per patient. RESULTS: A total of 27 HSRs occurred in 24 patients. No protective effect was observed for H2A when comparing paclitaxel injections with H2A premedication versus without H2A (OR = 1.12, p = 0.84). There was also no significant difference in risk of HSR for famotidine versus ranitidine (OR = 0.79, p = 0.78). However, the risk of HSRs was significantly lower for paclitaxel injections with corticosteroids than for those without (OR = 0.08, p = 0.03). In addition, the risk of HSR was significantly higher for the first, second, or third paclitaxel injections than for the subsequent injections (OR = 10.1, p < 0.001). CONCLUSION: We did not find substantial evidence of an increased risk of HSR due to the absence of H2A in the premedication protocols for paclitaxel. Thus, in contrary to the existing literature on paclitaxel, our findings support the use of a premedication protocol without H2A.

BACKGROUND: Personalized and effective treatments for pancreatic ductal adenocarcinoma (PDAC) continue to remain elusive. Novel clinical trial designs that enable continual and rapid evaluation of novel therapeutics are needed. Here, we describe a platform clinical trial to address this unmet need. METHODS: This is a phase II study using a Bayesian platform design to evaluate multiple experimental arms against a control arm in patients with PDAC. We first separate patients into three clinical stage groups of localized PDAC (resectable, borderline resectable, and locally advanced disease), and further divide each stage group based on treatment history (treatment naïve or previously treated). The clinical stage and treatment history therefore define 6 different cohorts, and each cohort has one control arm but may have one or more experimental arms running simultaneously. Within each cohort, adaptive randomization rules are applied and patients will be randomized to either an experimental arm or the control arm accordingly. The experimental arm(s) of each cohort are only compared to the applicable cohort specific control arm. Experimental arms may be added independently to one or more cohorts during the study. Multiple correlative studies for tissue, blood, and imaging are also incorporated. DISCUSSION: To date, PDAC has been treated as a single disease, despite knowledge that there is substantial heterogeneity in disease presentation and biology. It is recognized that the current approach of single arm phase II trials and traditional phase III randomized studies are not well-suited for more personalized treatment strategies in PDAC. The PIONEER Panc platform clinical trial is designed to overcome these challenges and help advance our treatment strategies for this deadly disease. TRIAL REGISTRATION: This study is approved by the Institutional Review Board (IRB) of MD Anderson Cancer Center, IRB-approved protocol 2020-0075. The PIONEER trial is registered at the US National Institutes of Health (ClinicalTrials.gov) NCT04481204 .

BACKGROUND: WAGR syndrome (Wilms tumor, aniridia, genitourinary anomalies, and range of developmental delays) is a rare contiguous gene deletion syndrome with a 45% to 60% risk of developing Wilms tumor (WT). Currently, surveillance and treatment recommendations are based on limited evidence. METHODS: Clinical characteristics, treatments, and outcomes were analyzed for patients with WAGR and WT/nephroblastomatosis who were identified through International Society of Pediatric Oncology Renal Tumor Study Group (SIOP-RTSG) registries and the SIOP-RTSG network (1989-2019). Events were defined as relapse, metachronous tumors, or death. RESULTS: Forty-three patients were identified. The median age at WT/nephroblastomatosis diagnosis was 22 months (range, 6-44 months). The overall stage was available for 40 patients, including 15 (37.5%) with bilateral disease and none with metastatic disease. Histology was available for 42 patients; 6 nephroblastomatosis without further WT and 36 WT, including 19 stromal WT (52.8%), 12 mixed WT (33.3%), 1 regressive WT (2.8%) and 2 other/indeterminable WT (5.6%). Blastemal type WT occurred in 2 patients (5.6%) after prolonged treatment for nephroblastomatosis; anaplasia was not reported. Nephrogenic rests were present in 78.9%. Among patients with WT, the 5-year event-free survival rate was 84.3% (95% confidence interval, 72.4%-98.1%), and the overall survival rate was 91.2% (95% confidence interval, 82.1%-100%). Events (n = 6) did not include relapse, but contralateral tumor development (n = 3) occurred up to 7 years after the initial diagnosis, and 3 deaths were related to hepatotoxicity (n = 2) and obstructive ileus (n = 1). CONCLUSIONS: Patients with WAGR have a high rate of bilateral disease and no metastatic or anaplastic tumors. Although they can be treated according to existing WT protocols, intensive monitoring of toxicity and surveillance of the remaining kidney(s) are advised. LAY SUMMARY: WAGR syndrome (Wilms tumor, aniridia, genitourinary anomalies, and range of developmental delays) is a rare genetic condition with an increased risk of developing Wilms tumor. In this study, 43 patients with WAGR and Wilms tumor (or Wilms tumor precursor lesions/nephroblastomatosis) were identified through the international registry of the International Society of Pediatric Oncology Renal Tumor Study Group (SIOP-RTSG) and the SIOP-RTSG network. In many patients (37.5%), both kidneys were affected. Disease spread to other organs (metastases) did not occur. Overall, this study demonstrates that patients with WAGR syndrome and Wilms tumor can be treated according to existing protocols. However, intensive monitoring of treatment complications and surveillance of the remaining kidney(s) are advised.

PURPOSE: The aim of the World Health Organization-International Paediatric Oncology Society is to improve childhood cancer survival in low- and middle-income countries to 60% by 2030. This can be achieved using standardised evidence-based national treatment protocols for common childhood cancers. The aim of the study was to describe the development and implementation of the SACCSG NB-2017 neuroblastoma (NB) treatment protocol as part of the treatment harmonisation process of the South African Children's Cancer Study Group. METHODS: The Consolidated Framework for Implementation Research was used to identify factors that could influence the implementation of the national NB protocol as a health care intervention. The evaluation was done according to five interactive domains for implementation: intervention characteristics, inner setting, outer setting, individual or team characteristics and the implementation process. RESULTS: The protocol was developed over 26 months by 26 physicians involved in childhood cancer management. The process included an organisational phase, a resource identification phase, a development phase and a research ethics approval phase. Challenges included nationalised inertia, variable research ethical approval procedures with delays and uncoordinated clinical trial implementation. CONCLUSION: The implementation of the national NB protocol demonstrated the complexity of the implementation of a national childhood cancer treatment protocol. However, standardised paediatric cancer treatment protocols based on local expertise and resources in limited settings are feasible.

BACKGROUND: The optimal treatment of stage IV rectal cancer remains controversial. The purpose of this study was to assess the treatment outcomes and toxicity of neoadjuvant chemotherapy and radiotherapy followed by local treatment of all tumor sites and subsequent adjuvant chemotherapy in stage IV rectal cancer patients with potentially resectable metastases. METHODS: Adult patients diagnosed with locally advanced rectal adenocarcinoma with potentially resectable metastases, who received neoadjuvant chemotherapy and radiotherapy from July 2013 and September 2019 at Sun Yat-sen University cancer center, were included. Completion of the whole treatment schedule, pathological response, treatment-related toxicity and survival were evaluated. RESULTS: A total of 228 patients were analyzed with a median follow-up of 33 (range 3.3 to 93.4) months. Eventually, 112 (49.1%) patients finished the whole treatment schedule, of which complete response of all tumor sites and pathological downstaging of the rectal tumor were observed in three (2.7%) and 90 (80.4%) patients. The three-year overall survival (OS) and progression-free survival (PFS) of all patients were 56.6% (50.2 to 63.9%) and 38.6% (95% CI 32.5 to 45.8%), respectively. For patients who finished the treatment schedule, 3-year OS (74.4% vs 39.2%, P < 0.001) and 3-year PFS (45.5% vs 30.5%, P = 0.004) were significantly improved compared those who did not finish the treatment. Grade 3-4 chem-radiotherapy treatment toxicities were observed in 51 (22.4%) of all patients and surgical complications occurred in 22 (9.6%) of 142 patients who underwent surgery, respectively. CONCLUSIONS: Neoadjuvant chemotherapy and radiotherapy followed by resection/ablation and subsequent adjuvant chemotherapy offered chances of long-term survival with tolerable toxicities for selected patients with potentially resectable stage IV rectal cancer, and could be considered as an option in clinical practice.

Mixed phenotype acute leukemia (MPAL) is a rare type of leukemia with a limited number of studies conducted to characterize its clinical spectrum and most importantly the best treatment modality. MPAL blasts show more than one phenotype either myeloid/monocytic with T- or B-lymphoid or extremely rare triple lineage associated phenotypic markers. This study aimed to characterize MPAL cases with special emphasis on comparing adult and pediatric age groups, exploring treatment regimens, and clinical outcome. Among 2571 acute leukemia patients, 102 MPAL cases fulfilling the 2008/2016 WHO diagnostic criteria of MPAL were recruited in the study. The incidence of MPAL was 4% of acute leukemia patients. Pediatric cases were 54 (53%) while adults were 48/102 (47%). Myeloid/B-lymphoid phenotype was found in 86/102 (84%), with BCR-ABL fusion gene transcript detected in 14/102(13.7%) patients. ALL-like treatment showed better response rates as compared with the myeloid based regimen (p = 0.001). MPAL behaves in a manner that resembles in clinical features, their lymphoid progenitor counterpart leukemias both in adults and pediatric patients with superior treatment response to ALL-like regimen, especially in adults.

We have reported that a strict denosumab administration management system with oral calcium/vitamin D supplementation attenuates denosumab-induced hypocalcemia in 158 cancer patients with bone metastasis. In this report, 27.8% of the patients experienced hypocalcemia, including 0.6% with grade 2. So far, the risk factors for ≥grade 2 hypocalcemia incidence have been identified in denosumab-treated cancer patients, including patients without calcium/vitamin D supplementation. Therefore, the present study aimed to reveal the factors that affect all-grade hypocalcemia incidence with calcium/vitamin D supplementation and team medical care according to the management system. A receiver operating characteristic curve analysis suggested that the cutoff of baseline serum calcium level for all-grade hypocalcemia incidence was 9.3 mg/dL. Multivariate analysis revealed that age ≥65 years (odds ratio, 95% confidence interval: 2.57, 1.11-5.95, p = 0.03), grade 1 or higher serum alkaline phosphatase elevation (3.70, 1.71-8.00, p < 0.01), an adjusted serum calcium level of less than 9.3 mg/dL (3.21. 1.25-8.24, p = 0.02) at baseline, and co-administration of cytotoxic agents (2.33, 1.06-7.11, p = 0.03) are risk factors for the incidence of all-grade hypocalcemia. However, renal dysfunction, which has been suggested to be a risk factor in previous reports, was not a factor. In conclusion, we revealed the risk factors for all-grade hypocalcemia in calcium/vitamin D supplementation and awareness, as demonstrated by the management system. Moreover, renal dysfunction was not a risk factor in our strict denosumab administration management system. Our results support the value of early detection of hypocalcemia incidence to guide the selection of an appropriate management strategy.

Non-ionizing radiation is commonly used in the clinical setting, despite its known ability to trigger oxidative stress and apoptosis, which can lead to damage and cell death. Although induction of cell death is typically considered harmful, apoptosis can also be beneficial in the right context. For example, cell death can serve as the signal for new tissue growth, such as in apoptosis-induced proliferation. Recent data has shown that exposure to non-ionizing radiation (such as weak static magnetic fields, weak radiofrequency magnetic fields, and weak electromagnetic fields) is able to modulate proliferation, both in cell culture and in living organisms (for example during tissue regeneration). This occurs via in vivo changes in the levels of reactive oxygen species (ROS), which are canonical activators of apoptosis. This review will describe the literature that highlights the tantalizing possibility that non-ionizing radiation could be used to manipulate apoptosis-induced proliferation to either promote growth (for regenerative medicine) or inhibit it (for cancer therapies). However, as uncontrolled growth can lead to tumorigenesis, much more research into this exciting and developing area is needed in order to realize its promise.

BACKGROUND: Adolescent and young adult (AYA) cancer survivors have high risks of late effects. Little is known about the late-effect information needs of AYAs early in treatment or their role in treatment decision making. This study evaluated the importance, quality, and implications of information about late effects in AYAs recently diagnosed with cancer. METHODS: This study surveyed 201 AYAs with cancer who were 15 to 29 years old and were treated at the Dana-Farber Cancer Institute (Boston, Massachusetts). Patients were approached within 6 weeks of their diagnosis and were asked about their late-effect and infertility information needs, treatment decision making, and communication outcomes. RESULTS: Forty-five percent of the participants were female; 88% were white. Most AYAs (87% [173 of 200]) considered information about the risks of late effects to be extremely or very important; 80% (159 of 200) valued information about infertility. Many were distressed by information about late effects (53% [105 of 200]) and infertility (45% [89 of 200]); those who considered late-effect information distressing were more likely to value this information (P < .0001). Consideration of late effects (41% [82 of 201]) and infertility (36% [72 of 201]) greatly influenced many patients' treatment decision making. Although 92% of the patients (184 of 199) reported receiving high-quality information about the diagnosis, 57% (113 of 199; P < .0001) and 65% (130 of 199; P < .0001) felt that they had received high-quality information about late effects and infertility, respectively. CONCLUSIONS: Most AYAs with cancer value early information about the risks of late effects and infertility, yet many patients felt that they had not received high-quality information about these topics. The development of age-appropriate late-effect communication strategies that recognize high AYA distress may help to address the gap between desired information and perceived information quality.

PURPOSE OF REVIEW: Recommendations for intakes of nâ-â3 fatty acids (FAs) in patients who are receiving chemotherapy for cancer are based on weak evidence. This review highlights themes within the emergent literature to suggest improvements in the design of studies that provide nâ-â3 FA supplements concurrent with cytotoxic agents. RECENT FINDINGS: Following earlier research in animal models and human pilot studies, recent human studies have evaluated the effect of providing nâ-â3 FAs during delivery of single agent and multiagent chemotherapy regimens for breast and gastro-intestinal cancers. Regimens were based on platinum compounds, fluoropyrimidines or both, and a variety of additional agents. Tumor location and stage, supplement dose and duration, and endpoints were dissimilar across studies. Overall, the recent research continues to support the safety and tolerability of nâ-â3 FA supplementation with chemotherapy and provides additional evidence, albeit weak, for enhanced tumor response, maintenance of weight and muscle, and reduction in inflammation and toxicities in the host across multiple cancer sites and chemotherapy regimens. SUMMARY: The barriers to implementation in practice remain small study sizes, variations in supplement dosage and methodology, and differences in primary endpoints. Randomized, blinded trials with a justifiable sample size, adequate doses, monitored compliance and measures of clinically important endpoints are required to move these findings to a higher level of evidence for implementation into clinical practice.

Introduction: Population-based data on the implementation of guidelines for cancer patients in daily practice are scarce, while practice variation may influence patient outcomes. Therefore, we evaluated treatment patterns and associated variables in the systemic treatment of metastatic colorectal cancer (mCRC) in the Netherlands.Material and methods: We selected a random sample of adult mCRC patients diagnosed from 2008 to 2015 from the National Cancer Registry in 20 (4 academic, 8 teaching and 8 regional) Dutch hospitals. We examined the influence of patient, demographic and tumour characteristics on the odds of being treated with systemic therapy according to the current guideline and assessed its association with survival.Results: Our study population consisted of 2222 mCRC patients of whom 1307 patients received systemic therapy for mCRC. Practice variation was most obvious in the use of bevacizumab and anti-EGFR therapy in patients with (K)RAS wild-type tumours. Administration rates did not differ between hospital types but fluctuated between individual hospitals for bevacizumab (8-92%; p < .0001) and anti-EGFR therapy (10-75%; p = .05). Bevacizumab administration was inversely correlated to higher age (OR:0.2; 95%CI: 0.1-0.3) comorbidity (OR:0.6; 95%CI: 0.5-0.8) and the presence of metachronous metastases (OR:0.5; 95%CI: 0.3-0.7), but patient characteristics did not differ between hospitals with low or high bevacizumab administration rates. The hazard ratios for exposure to bevacizumab and anti-EGFR therapy were 0.8 (95%CI: 0.7-0.9) and 0.6 (95%CI: 0.5-0.8), respectively.Discussion: We identified significant inter-hospital variation in targeted therapy administration for mCRC patients, which may affect outcome. Age and comorbidity were inversely correlated with non-administration of bevacizumab but did not explain inter-hospital practice variation. Our data suggest that practice variation is based on individual strategy of hospitals rather than guideline recommendations or patient-driven decisions. Individual hospital strategies are an additional factor that may explain the observed differences between real-life data and results obtained from clinical trials.

OBJECTIVE: The aim of delivering radiotherapy for pancreatic ductal adenocarcinoma patients was to sterilize vessel margin, increase R0 resection rate and delay local progression. Whether preoperative radiotherapy could prolong overall survival of surgical candidates remained unknown. METHODS: Pancreatic ductal adenocarcinoma patients receiving radical resection from surveillance, epidemiology and end result database were enrolled. Propensity score matching was conducted to balance difference in baseline characteristics, and survival analyses were performed to compare overall survival between preoperative radiotherapy and upfront resection groups. Cox proportional hazard regression model and subgroup analyses were utilized to identify prognostic factors. RESULTS: A total of 11 665 and 597 pancreatic ductal adenocarcinoma patients receiving upfront resection and preoperative radiotherapy followed by resection from 2004 to 2016 were identified, respectively, while baseline characteristics were distinct between groups. After propensity score matching, preoperative radiotherapy was not associated with better overall survival (upfront resection vs preoperative radiotherapy, 26 vs 27 months). Subgroup analyses showed that preoperative radiotherapy was a protective factor in pT4 (hazard ratio = 0.64, 95% confidence interval: 0.47-0.88) but a negative predictor in pT1 (hazard ratio = 1.79, 95% confidence interval: 1.08-2.97) patient populations. Survival analyses showed that preoperative radiotherapy improved overall survival of patients with pT4 stage (upfront resection vs preoperative radiotherapy, 19 vs 25 months) and involvement of celiac axis, superior mesenteric artery and aorta (upfront resection vs preoperative radiotherapy, 20 vs 27 months), while preoperative radiotherapy was associated with worse overall survival in patients with pT1 tumor (upfront resection vs preoperative radiotherapy, 39 vs 24 months). CONCLUSION: Preoperative radiotherapy could improve survival of resected pancreatic ductal adenocarcinoma patients with pT4 stage or with celiac axis, superior mesenteric artery and aorta invasion.

PURPOSE: We explored how lifetime comorbidities and treatment-related cancer symptoms were associated with quality of life (QOL) in rural cancer survivors. METHODS: Survivors (n = 125) who were rural Illinois residents aged 18+ years old were recruited from January 2017 to September 2018. We conducted 4 multivariable regressions with QOL domains as outcomes (social well-being, functional well-being, mental health-MHQOL, physical health-PHQOL); the number of physical and psychological comorbidities (e.g., arthritis, high blood pressure, stroke) and treatment-related cancer symptoms (e.g., worrying, feeling sad, lack of appetite, lack of energy) as predictors; and, cancer-related and demographic factors related to these variables as covariates. RESULTS: The number of comorbidities and number of treatment-related symptoms were inversely associated with functional well-being (Std ß = - 0.36, p < 0.0001 and - 0.18, p = 0.03), and MHQOL (Std ß = - 0.30, p = 0.001 and Std ß = - 0.25, p = 0.004). Comorbidities were associated inversely with social well-being (Std ß = - 0.27, p = .003). Comorbidities and treatment-related symptoms were not associated with PHQOL (p = 0.20-0.24). Sensitivity analyses suggested that psychological comorbidities, treatment-related psychological symptoms, and physical comorbidities were associated with social well-being, functional well-being, and MHQOL. CONCLUSIONS: Our study highlights the utility of risk-based survivorship care plans to address the negative, additive impact of comorbidities and the treatment-related symptoms to improve the health-related QOL among rural survivors. Future research should assess how contextual factors (e.g., geographic distance to oncologists and other providers) should be incorporated in survivorship care planning and implementation for rural survivors.

Cancer patients are at higher risk to be infected with COVID-19 and to develop a more severe form. Breast cancer (BC) treatments, including chemotherapy (CT), targeted therapy and immunotherapy can weaken the immune system and possibly cause lung problems. For all these reasons Salah Azaiez Institute's department of Medical Oncology took drastic actions to protect patients. In this article we will discuss protocol adjustments taken during the COVID-19 pandemic for breast cancer patients.

One of the sequelae of head and neck cancer treatment is secondary lymphedema, with important impact on breathing, swallowing and vocal functions. The aim of the study was to assess the presence, staging characteristics and relationship of external and internal lymphedema and dysphagia after head and neck cancer treatment. The MDACC Lymphedema Rating Scale in Head and Neck Cancer was employed for the assessment and staging of face and neck lymphedema; the Radiotherapy Edema Scale for internal lymphedema; and a fiberoptic endoscopic evaluation of swallowing (FEES) for swallowing. The sample consisted of 46 patients with a diagnosis of head and neck cancer. Lymphedema was detected in 97.8% (45) of the evaluations with predominance of the composite type (73.9%-34). A high percentage of external lymphedema of the neck (71.7%-33) and submandibular (63%-29) were detected, with predominance of the more advanced levels. Internal edema was found in almost all structures and spaces at moderate/severe level. At FEES, residue (higher percentage in valleculae and pyriform sinus), penetration and aspirations were observed. The residue was detected in higher occurrence in patients with composite lymphedema (p = 0.012). The combined treatment with radiotherapy was related to submandibular external lymphedema (p = 0.009), altered pharyngolaryngeal sensitivity (0.040), presence of residue (p = 0.001) and penetration to pasty (p = 0.007) and internal edema in almost all structures. There was also a higher percentage of residue in cases with internal altered pharyngolaryngeal sensitivity, residue, penetration and aspiration. Combined treatment with radiotherapy is an associated factor of edema. Cervicofacial and pharyngolaryngeal lymphedema is a frequent event after treatment for HNC, with important impact on swallowing performance characterised by altered pharyngolaryngeal sensitivity, residue, penetration and aspiration. Combined treatment with radiotherapy is an associated factor.

The purpose of this study was to investigate doctors' and patients' perceptions of cervical intraepithelial neoplasia 1 (CIN 1) and its treatment methods. A survey questionnaire was offered to obstetrics and gynaecology doctors and patients with CIN 1 in 2017. Only 43% of patients knew of this disease. Regarding perceptions of its aetiology, 64% of the patients perceived human papillomavirus infection to be the main cause of CIN 1. Patients' most preferred treatments were medication (20%), followed by alternative treatment (14%). Among doctors, regular follow-up was the most preferred method for managing CIN 1. The survey showed that current treatment modalities for CIN 1 were satisfactory to only half of doctors (50%) and patients (53%). Overall, 70% of doctors responded that new drug development for CIN 1 is needed. Although, CIN 1 is a low-grade lesion, doctors and patients expressed the desire for new therapeutic agents to manage it.IMPACT STATEMENTWhat is already known on this subject? In general, treatment is not recommended for CIN 1 because lesions are considered indicative of transient HPV infection and spontaneously regress in most patients.What do the results of this study add? Regular follow-up for CIN 1 were satisfactory to only half of doctors and patients. Thirty-six percent of patients wanted active treatment instead of regular follow-up. In addition, 70% of doctors responded that new drug development for CIN 1 is needed.What are the implications of these findings for clinical practice and/or further research? Our results support the need for therapeutic agents for CIN 1.

BACKGROUND: Primary central nervous system lymphoma (PCNSL) is a diffuse large B-cell lymphoma (DLBCL) confined to the central nervous system (CNS) with rising incidence among patients > 65 years. Although elderly patients are able to tolerate aggressive systemic chemotherapy, previous studies have demonstrated inferior outcomes for patients who present with a poor performance status (PS) and older age. Usually, intensive treatment approaches including high-dose chemotherapy followed by autologous stem cell transplantation (HDT-ASCT) are only offered to patients younger than 65-70 years of age. METHODS: This is an open-label, multicentric, non-randomized, single arm phase II trial. We will recruit 51 immuno-competent patients with newly diagnosed PCNSL from 12 German centers. The objective is to investigate the efficacy of age-adapted induction treatment followed by HDT-ASCT. All enrolled patients will undergo induction chemotherapy consisting of 2 cycles of rituximab 375 mg/m2/d (days 0 & 4), methotrexate 3.5 g/m2 (d1), and cytarabine 2 × 2 g/m2/d (d2-3) every 21 days. After 2 cycles of induction chemotherapy, patients achieving at least stable disease will undergo HDT-ASCT with busulfan 3.2 mg/kg/d (days - 7-(- 6)) and thiotepa 5 mg/kg/d (days - 5-(- 4)) followed by autologous stem cell transplantation. The primary endpoint of this study is 1-year progression-free survival (PFS). Secondary endpoints include PFS, overall survival, treatment response and treatment-related morbidities. Minimal follow-up after treatment completion is 12 months. DISCUSSION: Current treatment options for PCNSL have improved over the last years, resulting in the potential to achieve durable remission or cure in patients < 70 years. Age alone may not be the only criterion to select patients for this effective treatment approach and probably many elderly patients are undertreated just because of advanced age. There have been no multicentre trials investigating this curative treatment concept in elderly and fit PCNSL patients so far. We aim to answer whether HDT-ASCT is feasible and effective in fit patients > 65 years with newly-diagnosed PCNSL. TRIAL REGISTRATION: German clinical trials registry DRKS00011932 registered 18 August 2017.

BACKGROUND: Gastric cancer ranks the fifth most common cancer, and the third leading cause of cancer-related deaths worldwide. Gastric cancer with liver metastasis (GCLM) has devastating prognosis, however, optimal treatment of GCLM, especially in elderly patients, has yet to be clarified. CASE PRESENTATION: A 75-year-old man was diagnosed with advanced gastric cancer (GC), presenting with acute gastrointestinal bleeding and synchronous metastatic lesion in liver. Based on multidisciplinary team (MDT)'s decision, this patient underwent distal palliative gastrectomy with R1 margin. Histopathological diagnosis was stage IV gastric adenocarcinoma (pT3N2M1), HER2 negative. The patient was treated with chemotherapy and argon-helium cryoablation of liver and lung metastases.HER-2 gene amplification was identified in peripheral blood at later stage of therapy. The patient had been followed-up for 39 months, in sharp contrast to a median survival time of 13.8 months for majority of advanced GC. CONCLUSIONS: Palliative distal gastrectomy in combination with chemotherapy and cryoablation significantly prolongs overall survival of an elderly patient with GCLM.
