Is there scope to do better? Clinical communication with adolescents and young adults with cancer-A scoping review.

INTRODUCTION: How to communicate effectively with adolescent and young adults with cancer (AYACs) is a research priority. In a UK-wide survey of young people with cancer's research priorities, communication was a striking cross-cutting theme. It is increasingly recognised that AYACs have experiences and communication needs that differ significantly from those of younger children and older adults. The purpose of this review is to explore the features of effective clinical communication with AYACs. METHODS: A literature search was undertaken to identify and map the available evidence using a broad scope to get an overview of the pertinent literature, identify knowledge gaps and clarify concepts. The searches yielded 5825 records, generating 4040 unique articles. These were screened and 71 full articles were read by four researchers with disagreements resolved by discussion leaving 29 included articles. Narrative synthesis was undertaken in relation to each of the research questions. RESULTS: Three key themes were identified: being an adolescent/young adult, supporters, and healthcare professionals (HCPs). AYACs need to feel that HCPs understand their unique perspective. They want to be involved, this changes over time and in different contexts. Supporters are a central tenet, are most often parents and undertake several roles which are not always universally supportive. HCPs enable involvement of AYACs, and this needs to be actively promoted. AYACs preference for their level of involvement requires continual assessment. The three themes are interlinked and exist within the wider scope of the triadic encounter and cancer experience. CONCLUSION: Supporters, most often parents were a key feature across the data and were seemingly paradoxical in nature. Triadic communication, the presence of a third person, is a central tenet of communication with AYACs and we propose a conceptual model to represent the nuances, components, and facets of this complex communication.

Triadic communication with teenagers and young adults with cancer: a systematic literature review - 'make me feel like I'm not the third person'.

OBJECTIVES: Clinical communication needs of teenagers and young adults with cancer (TYACs) are increasingly recognised to differ significantly from younger children and older adults. We sought to understand who is present with TYACs, TYACs' experiences of triadic communication and its impact. We generated three research questions to focus this review: (1) Who is present with TYACs in healthcare consultations/communication?, (2) What are TYACs' experiences of communication with the supporter present? and (3) What is the impact of a TYAC's supporter being present in the communication? DESIGN: Systematic review with narrative synthesis. DATA SOURCES: The search was conducted across six databases: Medline, CINAHL, Embase, PsycINFO, Web of Science and AMED for all publications up to December 2023. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Included papers were empirical research published after 2005; participants had malignant disease, diagnosed aged 13-24 years (for over 50% of participants); the research addressed any area of clinical communication. DATA EXTRACTION AND SYNTHESIS: Three independent reviewers undertook full-text screening. A review-specific data extraction form was used to record participant characteristics and methods from each included paper and results relevant to the three review questions. RESULTS: A total of 8480 studies were identified in the search, of which 36 fulfilled the inclusion criteria. We found that mothers were the most common supporter present in clinical communication encounters. TYACs' experiences of triadic communication are paradoxical in nature-the supporter can help or hinder the involvement of the young person in care-related communication. Overall, young people are not included in clinical communication and decisions at their preferred level. CONCLUSION: Triadic communication in TYACs' care is common, complex and dynamic. Due to the degree of challenge and nuances raised, healthcare professionals need further training on effective triadic communication. PROSPERO REGISTRATION NUMBER: CRD42022374528.

"Absolutely No One Else, Other Than Yourself": Experiences of Adolescents and Young Adults with Cancer During the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic caused widespread disruption to the provision of health care in the United Kingdom. It posed two risks to AYACs: disruption of care and long-term adverse consequences compounding late effects. This study sought to better understand the experiences of AYACs receiving care during the pandemic and identify areas where greater support is needed. Methods: In-depth semistructured interviews with AYACs (n = 6), 16-22 years at diagnosis. Interviews were transcribed verbatim and analyzed using the principles of Giorgi's phenomenological analysis. Results: Four major themes and an interconnected theme were identified. Changes to health care meant AYACs were isolated and loss of in-person follow-up caused anxiety (theme 1). AYACs had to adapt to life with COVID-19 restrictions (theme 2). Support during the pandemic came from a variety of sources (theme 3). AYACs reported poor mental health due to a fear of relapse and contracting COVID-19 (theme 4). An additional burden for AYACs was the loss of the third person (e.g., parent) in consultations (interconnected theme). Conclusion: This study has wider implications for delivery of AYAC care, despite being set during the COVID-19 pandemic. The mental health implications will impact long-term care of these patients, and health care professionals must be aware of these to meet AYACs' holistic care needs.

Radiation-induced angiosarcoma of the breast: retrospective analysis at a regional treatment centre.

BACKGROUND: Radiation-induced angiosarcoma (RIA) is an uncommon but morbid complication after radiotherapy for breast cancer. METHODS: Retrospective analysis of breast RIA patients at Cambridge University Hospital (CUH), a regional treatment centre in the East of England. RESULTS: 22 patients were identified between 2010 and 2022. Median age of diagnosis was 65 years (range 41-78). Median time from breast radiotherapy to RIA diagnosis was 6.5 years (range 2.4-16.0)-this interval has decreased over the last 24 years (r2 = 0.6601). 9% had metastasis at presentation. All patients underwent surgery (55% at CUH, 45% at local hospitals). 27% received peri-operative pegylated liposomal doxorubicin in the first-line setting. 62% relapsed following their primary curative-intent treatments after a median of 28 months. Metastases occurred in 36%, the commonest sites being lung (100%) and lymph node (50%). 2-year and 5-year overall survival (OS) rates for all patients were 73% and 60%, respectively. No correlation between progression-free survival (PFS) and OS was found with tumour size, margin, peri-operative chemotherapy, and whether surgery was performed at CUH. Patients with multifocal disease on their breasts had shorter PFS following surgery compared to single-lesion disease (median 10 vs 65 months; HR = 4.359 [95% CI 1.342-14.16]; P = 0.0143). Patients aged > 72 years had a median OS of 45 months vs 102 months for those ≤ 72 years (HR = 7.129 [95% CI 1.646-30.88]; P = 0.0086). CONCLUSION: RIA has high rates of recurrence and mortality and appears to be occurring sooner after breast radiotherapy. Further studies on its pathogenesis and effective treatment are warranted.

Identification of an Activating PDGFRA Deletion in a Novel Sinonasal Soft Tissue Neoplasm.

BACKGROUND: Spindle cell tumours in the sinonasal area are diagnostically challenging. We identified a neoplasm that defied histopathological classification using current criteria. METHODS: The case was subjected to histopathological, immunohistochemical and molecular analysis using a large small variant DNA panel. RESULTS: The tumour comprised cytologically bland epithelioid spindle cells with a rich vasculature, which lack expression of actin and other smooth muscle markers, CD34 and beta-catenin. An activating insertion/deletion in exon 12 of the PDGFRA gene was detected. This alteration has previously been described in gastrointestinal stromal tumours and inflammatory fibroid polyps of the GI tract, but the site, histological, and immunophenotypic features in this tumour are distinct. CONCLUSION: We describe a novel sinonasal spindle cell tumour characterised by an activating insertion/deletion in exon 12 of PDGFRA. The diagnosis of PDGFRA-activated sinonasal spindle cell tumour should be considered in difficult to classify mesenchymal lesions at this site.

Selinexor in Advanced, Metastatic Dedifferentiated Liposarcoma: A Multinational, Randomized, Double-Blind, Placebo-Controlled Trial.

PURPOSE: Antitumor activity in preclinical models and a phase I study of patients with dedifferentiated liposarcoma (DD-LPS) was observed with selinexor. We evaluated the clinical benefit of selinexor in patients with previously treated DD-LPS whose sarcoma progressed on approved agents. METHODS: SEAL was a phase II-III, multicenter, randomized, double-blind, placebo-controlled study. Patients age 12 years or older with advanced DD-LPS who had received two-five lines of therapy were randomly assigned (2:1) to selinexor (60 mg) or placebo twice weekly in 6-week cycles (crossover permitted). The primary end point was progression-free survival (PFS). Patients who received at least one dose of study treatment were included for safety analysis (ClinicalTrials.gov identifier: NCT02606461). RESULTS: Two hundred eighty-five patients were enrolled (selinexor, n = 188; placebo, n = 97). PFS was significantly longer with selinexor versus placebo: hazard ratio (HR) 0.70 (95% CI, 0.52 to 0.95; one-sided P = .011; medians 2.8 v 2.1 months), as was time to next treatment: HR 0.50 (95% CI, 0.37 to 0.66; one-sided P < .0001; medians 5.8 v 3.2 months). With crossover, no difference was observed in overall survival. The most common treatment-emergent adverse events of any grade versus grade 3 or 4 with selinexor were nausea (151 [80.7%] v 11 [5.9]), decreased appetite (113 [60.4%] v 14 [7.5%]), and fatigue (96 [51.3%] v 12 [6.4%]). Four (2.1%) and three (3.1%) patients died in the selinexor and placebo arms, respectively. Exploratory RNA sequencing analysis identified that the absence of CALB1 expression was associated with longer PFS with selinexor compared with placebo (median 6.9 v 2.2 months; HR, 0.19; P = .001). CONCLUSION: Patients with advanced, refractory DD-LPS showed improved PFS and time to next treatment with selinexor compared with placebo. Supportive care and dose reductions mitigated side effects of selinexor. Prospective validation of CALB1 expression as a predictive biomarker for selinexor in DD-LPS is warranted.

Documentation of Oncofertility Communication in Adolescents and Young Adults with Cancer: A Retrospective Analysis.

Background: Increasing numbers of adolescents and young adults with cancer (AYACs) are surviving long term, highlighting the importance of effective oncofertility communication. We undertook this study to understand documentation of fertility discussions with AYACs, what options are offered, and how this differs for AYACs on treatment compared with those post-treatment. Methods: We reviewed the documentation of fertility discussions with 122 AYACs treated between 2000 and 2020: 72 AYACs on treatment and 50 AYACs at least 3 years post-treatment ("late effects" cohort). Results: Diagnoses were split evenly between hematological and solid tumor diagnoses, and biological sex. Seventy-five percent of patients were diagnosed and treated by the AYAC team and 25% by the pediatric team. Median age at diagnosis was 19 years (range 4-24) for on-treatment patients and 16 years (range 3-25) for late effects patients. Fertility was discussed with 93% of on-treatment patients and 48% of late effects patients. Seventy-nine percent of on-treatment patients and 48% of late effects patients pursued a pre-treatment fertility preservation option. Post-treatment, 84% of late effects patients had a discussion and 57% pursued an option. Only four patients across both cohorts underwent oocyte or ovarian tissue cryopreservation. Those referred to specialist reproductive medicine clinics had more detailed documentation about fertility discussions. Nurse-led late effects clinics had a key role in facilitating post-treatment discussions. Conclusions: It is important to communicate oncofertility options to AYACs repeatedly throughout treatment. Referral to specialist oncofertility services and adequate information for both sexes is important pre-treatment, and can be facilitated post-treatment by a late effects service.

Adolescent and Young Adult Cancer Placements: Developing Complex Clinical Communication Skills of Medical Students.

Purpose: Following implementation of a student selected module in adolescent and young adult cancer care for medical students, we sought to explore their experiences of the specialty. Methods: We undertook a focus group of five medical students all in their fourth to sixth year of study. Transcripts were transcribed verbatim and analyzed thematically. Results: We identified six key themes repeatedly elicited during the focus group; these were specialized and holistic care, patient's perspective, connectedness and professional boundaries, triadic communication, emotional impacts, and professional development and support. Conclusion: Early exposure to this specialty is positive for students and the model could be replicated elsewhere.

"A Different Person Entirely": Adolescent and Young Adults' Experiences Returning to Education after Cancer Treatment.

Purpose: Adolescent and young adults (AYAs) establish their independent, adult identities as part of their psychosocial development, a process that is largely informed by educational experiences. Not only is a cancer diagnosis disruptive to this process but also AYA cancer survivors (AYACs) face barriers as they attempt to reintegrate into educational systems. This study explores the experiences of AYACs as they return to education, to identify these obstacles and the implications for care teams. Methods: In-depth semistructured interviews were conducted with AYACs (n = 8), 16-19 years of age at diagnosis and 18-27 years of age at time of interview. Interviews were transcribed verbatim and analyzed using the principles of Giorgi's phenomenological analysis. Results: Four major themes were identified: AYACs suffer from debilitating late effects (theme 1) post-treatment as they adjust to a loss of normality and other fundamental losses (theme 2) associated with a cancer diagnosis, such as irrecoverable future plans. The educational systems (theme 3) to which they return can be both accommodating, capable of making allowances, and uncompromising, unable to adapt to AYAC survivors' needs. Appropriate mechanisms to facilitate resilience (theme 4) among AYACs are vital for successful return to education. Conclusion: This study supports previous findings that late effects and systemic barriers can hinder return to education, but further research focused on this age group is required. We believe that treating clinicians and specialist services can facilitate the return of AYACs to education by providing warning and comprehensive information about late effects, as early as possible before treatment completion, as well as effective information sharing with educational institutions.

Lorlatinib for the treatment of inflammatory myofibroblastic tumour with TPM4-ALK fusion following failure of entrectinib.

Inflammatory myofibroblastic tumour (IMT) is a rare malignancy with limited responses to corticosteroids and chemotherapy. About half of cases have activating rearrangements in the ALK gene which could be targeted with ALK inhibitors. A 40-year-old man presented with a large right lung mass and nodal, trapezius and cerebral metastases. Biopsy confirmed IMT with TPM4-ALK fusion. He was treated with prednisolone without clinical benefit. He received the Trk/ROS1/ALK inhibitor entrectinib in a clinical trial but his disease progressed in less than 3 months. Ifosfamide and etoposide in addition to radiotherapy to the brain and chest were administered. Transient improvement in the radiotherapy-treated areas was observed but his disease progressed shortly afterwards on all sites including the development of new adrenal metastasis. Compassionate use of the third-generation ALK inhibitor lorlatinib resulted in excellent partial response on all disease sites after 2 months, followed by a further 6 months of disease stabilisation. Repeat imaging showed slight increase in size of the cerebral metastasis but stable disease elsewhere, for which he was given stereotactic radiotherapy. His disease progressed 3 months later and lorlatinib was substituted with another ALK inhibitor brigatinib but he deteriorated and died shortly afterwards. Our patient tolerated lorlatinib well for 11 months with minimal toxicities, although he developed unilateral right-sided lung consolidation that was probably related to a combination of infection, radiotherapy and lorlatinib, which needed treatment with antibiotics and corticosteroids. This case demonstrates a role of lorlatinib in the treatment of TPM4-ALK-rearranged IMT despite failure of entrectinib.

A randomized double-blind phase II study evaluating the role of maintenance therapy with cabozantinib in high-grade uterine sarcoma after stabilization or response to doxorubicin ± ifosfamide following surgery or in metastatic first line treatment (EORTC62113).

BACKGROUND: Uterine sarcomas are a group of rare tumors that include different subtypes. Patients with histopathological high-grade diseases are at high-risk of recurrence or progression, and have a poor prognosis. We aim to explore the most appropriate management in patients with uterine high-grade sarcomas. PRIMARY OBJECTIVE: To assess the efficacy of maintenance treatment with cabozantinib in patients with high-grade uterine sarcomas who achieved clinical benefit after standard chemotherapy. STUDY HYPOTHESIS: Maintenance treatment with cabozantinib after standard chemotherapy given as an adjuvant treatment after curative surgery, or in locally advanced or metastatic disease, increases progression-free survival compared with placebo TRIAL DESIGN: This is a randomized double blinded phase II trial. MAJOR INCLUSION/EXCLUSION CRITERIA: The study is enrolling adult patients with high-grade undifferentiated uterine sarcomas, high-grade endometrial stromal sarcomas, high-grade leiomyosarcoma, and high-grade adenosarcoma, FIGO (Federation International gynecologue Obstétricien) stage II/III to IV in stable disease or who achieved complete or partial response with doxorubicin ± ifosfamide, who are assigned 1:1 to 60 mg daily cabozantinib (experimental arm) or placebo (control arm), as maintenance therapy. Exclusion criteria include low-grade sarcoma. PRIMARY ENDPOINT: Progression-free survival at 4 months. SAMPLE SIZE: The study plans to enroll 90 patients to allow the randomization of 54 patients to detect an improvement in 4-month progression-free survival from 50% to 80% with 15% significance level and 85% power. Estimated dates for accrual completion: recruitment for the trial started in February 2015, and has currently enrolled 83 patients, of whom 35 patients have been randomized. The end of recruitment is anticipated for December 2020. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, number NCT01979393.

How Can Health Care Professionals Communicate Effectively with Adolescent and Young Adults Who Have Completed Cancer Treatment? A Systematic Review.

Communication with teenage and young adult or adolescent and young adult (AYA) patients with cancer is critically important and not consistently taught in health care education. We have developed a local training for medical students to experience and join AYA cancer consultations to improve clinicians' abilities in the future. We have undertaken a systematic review of the literature, to provide a comprehensive overview of studies evaluating communication in this specific patient group, to guide clinical practice and future research. We searched MEDLINE, EMBASE, PsycINFO, Web of Science, and CINAHL databases for literature containing data relating to communication in AYAs previously treated for malignant disease. To ensure as comprehensive a review as possible, the researchers defined the AYA age range using the extremes used globally: 13-39 years. Two thousand eight hundred and thirty-seven articles were identified, which were reduced to 1517 after duplicates were removed. After handsearching references and citation tracking, 1556 abstracts were screened of which 40 full-text articles were assessed for eligibility. Only 12 met all inclusion criteria and were included in the final analysis. Young people want to be heard and have trust in their health care professionals (HCPs). They want to be involved in decisions about their care, and HCPs must establish who else the AYA wants to be involved in the decision-making process. AYAs want information to be given in an amount they can control and at a time preferred by them. Further education of communication skills, especially triadic communication, is essential for professionals involved in AYA care.

Cardiotoxicity with trabectedin in the treatment of advanced soft tissue sarcoma.

Trabectedin is used routinely in the palliative management of patients with advanced soft tissue sarcoma. It is not generally considered to be cardiotoxic, and there is no specific caution for its use in patients with a history of cardiac disease or risk factors. Here, we report six cases from a single academic centre where life-threatening cardiotoxicity occurred acutely during treatment with trabectedin. These patients had a median age of 72.5 years (range: 68-81) at presentation with cardiotoxicity, significantly higher than the median ages of patients treated with trabectedin in clinical trials. Cardiotoxicity occurred between cycle 1, day 10, and cycle 5, day 5 of treatment (with three events occurring during cycle 2, and one during cycle 3). Two patients had a previous cardiac history and three patients had other relevant cardiac risk factors. Five patients had been treated previously with anthracyclines. Two patients developed acute pulmonary oedema, two developed fast atrial fibrillation, one developed an ST-elevation myocardial infarction and one suffered a fatal cardiac arrest. Two had unequivocal evidence of myocardial ischaemia, and two events were acutely fatal. Trabectedin was immediately discontinued in all cases and, for the four nonfatal events, there were no recurrences of the cardiac events. As no other definitive precipitants were identified, we consider these events to be related to trabectedin toxicity. We therefore urge caution with the use of trabectedin in elderly patients, and those with a previous cardiac history, abnormal cardiac function or significant cardiac risk factors including pericardiac lesions (present in two cases reported here).

Adjuvant Gemcitabine Plus Docetaxel Followed by Doxorubicin Versus Observation for High-Grade Uterine Leiomyosarcoma: A Phase III NRG Oncology/Gynecologic Oncology Group Study.

PURPOSE: We conducted a randomized phase III trial to determine whether adjuvant chemotherapy improves survival in women with uterine leiomyosarcoma. METHODS: Women with uterus-confined, high-grade leiomyosarcoma who were confirmed disease free by imaging were randomly assigned to four cycles of gemcitabine plus docetaxel, followed by four cycles of doxorubicin, or to observation. All were followed for evidence of recurrence. The primary end point was overall survival (OS). RESULTS: With international collaboration, 38 of the targeted accrual of 216 patients were enrolled, after which the study was closed by the National Cancer Institute for accrual futility. Twenty patients were assigned to chemotherapy, 18 to observation. Among the 17 patients treated with at least one cycle of chemotherapy, grade 3 or 4 toxicities were observed in 47%; among the 18 patients assigned to observation, one had grade 3 hypertension. There were six deaths (chemotherapy, n = 5; observation, n = 1), all due to disease. The restricted mean survival time for OS was estimated as 34.3 months (95% CI, 25.3 to 43.3 months) in the chemotherapy arm and as 46.4 months (95% CI, 43.6 to 49.1 months) in the observation arm. There were eight recurrences in each arm. The restricted mean survival time for recurrence-free survival was estimated as 18.1 (95% CI, 14.2 to 22.0) months in the chemotherapy arm and as 14.6 months (95% CI, 10.3 to 19.0 months) in the observation arm. Neither survival outcome comparison was considered statistically robust, due to the small sample size. CONCLUSION: Despite international collaboration to test the role of adjuvant chemotherapy in uterine-confined leiomyosarcoma, this study was closed for accrual futility. Although the sample size precludes robust statistical comparison, observed OS and recurrence-free survival data do not show superior outcomes with adjuvant chemotherapy.

Cancer-Related Fatigue in Adolescents and Young Adults After Cancer Treatment: Persistent and Poorly Managed.

Cancer-related fatigue is the most prevalent and distressing symptom experienced by adolescents and young adults (AYAs). An electronic survey was undertaken to ascertain current fatigue management and perceptions of its effectiveness. Eighty-five percent of responders (68/80) experienced fatigue, and it was worse more than 1 year after cancer treatment ended, compared to <1 year (p = 0.007). Forty-one percent received no fatigue management. Although advice to exercise was the most frequent intervention, the greatest impact of fatigue was on the ability to exercise and most did not find exercise advice helpful. Early intervention is warranted, supporting AYAs to persevere with increasing activity.

Pazopanib, a promising option for the treatment of aggressive fibromatosis.

Desmoid tumour/aggressive fibromatosis (DT/AF) is a rare soft-tissue neoplasm that is locally aggressive but does not metastasize. There is no standard systemic treatment for symptomatic patients, although a number of agents are used. Tyrosine kinase inhibitors have recently been reported to show useful activity. We reviewed our bi-institutional (Royal Marsden Hospital, Cambridge University Hospitals) experience with the tyrosine kinase inhibitor pazopanib in the treatment of progressing DT/AF. Eight patients with DT/AF were treated with pazopanib at Royal Marsden Hospital and Cambridge University Hospitals between June 2012 and June 2016. The median age of the patients was 37.5 (range: 27-60) years. The median duration of pazopanib treatment was 12 (range: 5-22) months and for three patients the treatment is ongoing. Three patients discontinued treatment early (patient preference, intolerable toxicity and logistical reasons, respectively). None of the patients showed radiological progression while on treatment, best responses according to Response Evaluation Criteria In Solid Tumors 1.1 were partial response in 3/8 and stable disease in 5/8 cases. Six patients derived clinical benefit from treatment in terms of improved function and/or pain reduction. Median progression-free survival was 13.5 (5-36) months. Only one patient experienced intolerable toxicity (grade 3 hypertension) leading to early treatment discontinuation. In our series of patients with DT/AF, pazopanib demonstrated important activity both in terms of symptom control (75%) and absence of radiological progression (100%). Results of ongoing confirmatory trials are eagerly awaited.

A Comprehensive Single Institutional Review of 2 Years in a Designated Fast-Track Sarcoma Diagnostic Clinic Linked with a Sarcoma Specialist Advisory Group: Meeting the Target but Failing the Task?

Background. National guidelines prompted the implementation of a designated two-week wait referral pathway to facilitate the early diagnosis of sarcomas, to improve treatment outcomes. Methods. Patients referred to the Cambridge Sarcoma Diagnostic Clinic between January 2013 and December 2014 were identified through the electronic appointments system. Information was retrospectively retrieved about patient characteristics and details of the diagnostic pathway. Results. 17.3% of patients referred (69/397) were diagnosed with a malignancy. Of these, 59.3% (41/69) had primary sarcomas, 17.4% (12/69) had metastatic cancer, and 23.2% (16/69) had a different primary malignancy. 15% of the 41 sarcomas were <5 cm, 34% in the 5-10 cm range, and 51% >10 cm. Sarcomas diagnosed through this clinic represented 13% (41/315) of sarcomas managed at the centre during the same 2 years. Conclusion. While we achieved the target of 10% (41/397) sarcoma diagnosis rate in the rapid access clinic, only 15% of these were <5 cm better prognosis lesions. This calls into question the "real world" impact of such diagnostic clinics on early diagnosis of sarcomas. In order to enhance generic cancer diagnostic skills, training in these diagnostic clinics could be usefully integrated into national training curricula for both surgical and nonsurgical oncologists.

Intensive cisplatin/oral etoposide for epithelial ovarian cancer: the Cambridge Gynae-Oncology Centre experience: too toxic for relapse?

Intensive cisplatin and oral etoposide for relapsed epithelial ovarian cancer (EOC), commonly known as the van der Burg (VDB) protocol, has been reported to improve response rates and progression-free survival. We report on all patients with relapsed EOC treated on the VDB protocol at the Cambridge Gynae-Oncology Centre. From the institutional databases, we identified all patients treated since 2001. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used Cox regression to identify predictors of survival. A total of 35 patients were treated on the VDB protocol. Toxicity was significant, with grade 3/4 fatigue, nausea and vomiting affecting 46, 46 and 29% of patients, respectively. Six patients had grade 3/4 infection and four (11%) deaths occurred on treatment. Efficacy was encouraging, with a radiological response rate of 43%, a median progression-free survival of 5.8 months and a median overall survival of 14.1 months. No significant difference in efficacy was seen between platinum-resistant and sensitive patients. We report significant activity of the VDB protocol in a routine clinical setting. However, the high rates of serious toxicity and treatment-related deaths among patients treated with palliative intent proved unacceptable. The Cambridge Gynae-Oncology Centre no longer uses this regimen in women with relapsed EOC.

Epirubicin, Cisplatin, and Capecitabine for Primary Platinum-Resistant or Platinum-Refractory Epithelial Ovarian Cancer: Results of a Retrospective, Single-Institution Study.

OBJECTIVE: Primary platinum-resistant epithelial ovarian cancer (EOC) is an area of unmet medical need. There is limited evidence from small studies that platinum-based combinations can overcome "resistance" in a proportion of patients. We investigated the efficacy and toxicity of platinum-based combination chemotherapy in the platinum-resistant and platinum-refractory setting. METHODS: Epirubicin, cisplatin, and capecitabine (ECX) combination chemotherapy was used at our institution for the treatment of relapsed EOC. From the institutional database, we identified all patients with primary platinum-refractory or platinum-resistant relapse treated with ECX as second-line therapy between 2001 and 2012. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used logistic and Cox regression models to identify predictors of response and survival respectively. RESULTS: Thirty-four 34 patients (8 refractory, 26 resistant) were treated with ECX. Response Evaluation Criteria In Solid Tumors (RECIST) response rate was 45%, median progression-free survival (PFS) was 6.4 months, and overall survival (OS) was 10.6 months. Platinum-resistant patients had better outcomes than did platinum-refractory patients (response rate, 54% vs 0%, P = 0.047; PFS 7.2 vs 1.8 months, P < 0.0001; OS 14.4 vs 3 months, P < 0.001). In regression models, time to progression after first-line treatment and platinum-refractory status were the strongest predictors of response and PFS or OS, respectively. Patients with time to progression after first-line treatment longer than 3 months showed PFS and OS of 7.9 and 14.7 months, respectively. Toxicity was manageable, with only 13% of cycles administered at reduced doses. CONCLUSIONS: Epirubicin, cisplatin, and capecitabine seems to be active in platinum-resistant relapsed EOC with manageable toxicity. Further prospective investigation of platinum-anthracycline combinations is warranted in patients who relapse 3 to 6 months after first-line platinum-taxane treatment.
