Late Relapse and Follow-up Protocols in Testicular Germ Cell Tumours: The Edinburgh Cancer Centre Experience and Review of the Literature

Aims To identify clinicopathological features and outcomes in patients with late relapse (LR) of testicular germ cell tumours (GCTs) in order to guide follow-up policy. Materials and Methods The Edinburgh Cancer Centre (ECC) database identified all patients diagnosed with testicular GCT between 1988 and 2002. Of 703 patients, six relapsed more than 24 months after their initial treatment. A retrospective casenote review was performed to extract clinical, pathological, treatment and outcome data. Results Six patients (0.85%) underwent late relapse. All patients presented initially with stage I disease and five were classified as good risk (International Germ Cell Consensus Classification, IGCCC). Median time to LR was 31 months. Two patients had previously relapsed less than 24 months from initial diagnosis. Markers at the time of relapse were normal in all patients. In all cases of late relapse disease was confined to axial lymphadenopathy. Three patients were treated with chemotherapy alone, two patients underwent surgical resection and one patient received combined treatment. All patients obtained a complete response and all remain disease free with a median follow-up of 52 months. Conclusions The incidence of late relapse in this series is low. Chemo-naive patients with LR were successfully salvaged with chemotherapy alone and patients previously exposed to cisplatin-based chemotherapy were salvaged with complete surgical excision. The optimal length of follow-up in patients with testicular germ cell tumours is not known and practice varies widely. In this cohort of 703 patients, only one patient who relapsed was picked up by additional clinic follow-up between 5 and 10 years. Thus, on the basis of this small series, the authors suggest that follow-up after five years may not be justified

Symptomatic leptomeningeal and intramedullary metastases from intracranial glioblastoma multiforme: A case report

Background. Glioblastoma multiforme infrequently metastasizes to the leptomeninges and even more rarely to the spinal cord. Moreover, very few patients with intracranial glioblastoma develop symptoms from spinal dissemination, with most patients not surviving long enough for spinal disease to become clinically evident. Case report. We present a rare case of symptomatic diffuse spinal leptomeningeal metastases simultaneously to an intramedullary lesion from an intracranial glioblastoma multiforme. After the diagnosis of spinal metastases the patient was treated with limited-field spinal radiotherapy (30 Gy in 3-Gy fractions). Results. Radiotherapy on the main spinal lesions provided either relief from pain or mild improvement of neurological deficits. The patient died due to intracranial progression 4 months after diagnosis of spinal seeding and 17 months after diagnosis of the primary disease. We analyzed leptomeningeal and spinal metastases from glioblastoma multiforme with reference to the literature. Conclusions. Radiotherapy for spinal disease may provide important symptom relief but the prognosis of these patients remains dramatically poor. As the local control of primary glioblastoma multiforme has improved with recent therapeutic advances, distant metastasis from high-grade gliomas is likely to become a more common clinical problem and such patients need to be included in clinical trials to evaluate new therapeutic approaches

Short-Term Pre-Harvest UV-B Supplement Enhances the Polyphenol Content and Antioxidant Capacity of Ocimum basilicum Leaves during Storage

Ocimum basilicum (basil) leaves are rich in polyphenols, conferring them a high antioxidant activity. The application of UV-B can be used to maintain the post-harvest nutraceutical quality of basil leaves. We aimed to investigate the effects of pre-harvest UV-B application on polyphenolic and pigment contents, antioxidant capacity, and the visual quality of basil stored leaves. We also evaluated the applicability of the non-invasive Dualex® for monitoring the accumulation of leaf epidermal phenolics (Flav Index). After exposing plants to white light (control) and to supplemental UV-B radiation for 4 d, the leaves were harvested and stored for 7d (TS7). The UV-B leaves showed both a higher phenolic content and antioxidant capacity than the controls at TS7. In addition, the correlations between the Flav Index and phenolic content demonstrated that Dualex® can reliably assess the content of epidermal phenolics, thus confirming its promising utilization as a non-destructive method for monitoring the phytochemical quality of O. basilicum leaves. In conclusion, a pre-harvesting UV-B application may be a tool for enhancing the content of polyphenols and the antioxidant potential of basil stored leaves without detrimental effects on their visual quality. These results are important considering the nutraceutical value of this plant and its wide commercial distribution

Quality of Life and Sexual Health in the Aging of PCa Survivors.

Prostate cancer (PCa) is the most common malignancy in elderly men. The progressive ageing of the world male population will further increase the need for tailored assessment and treatment of PCa patients. The determinant role of androgens and sexual hormones for PCa growth and progression has been established. However, several trials on androgens and PCa are recently focused on urinary continence, quality of life, and sexual function, suggesting a new point of view on the whole endocrinological aspect of PCa. During aging, metabolic syndrome, including diabetes, hypertension, dyslipidemia, and central obesity, can be associated with a chronic, low-grade inflammation of the prostate and with changes in the sex steroid pathways. These factors may affect both the carcinogenesis processes and treatment outcomes of PCa. Any treatment for PCa can have a long-lasting negative impact on quality of life and sexual health, which should be assessed by validated self-reported questionnaires. In particular, sexual health, urinary continence, and bowel function can be worsened after prostatectomy, radiotherapy, or hormone treatment, mostly in the elderly population. In the present review we summarized the current knowledge on the role of hormones, metabolic features, and primary treatments for PCa on the quality of life and sexual health of elderly Pca survivors

Radiotherapy in prostate cancer after kidney transplant: review of the literature and report of 6 cases

Background: Patients who received a kidney transplant (KT) are described in literature as a group with a higher incidence of malignant neoplasms compared to the general population. Cancer development after KT has become a major issue, as a remarkable percentage of patients are diagnosed with cancer. Treatment of prostate cancer (PCa) in renal transplant recipients (RTRs) is a challenging issue that has been discussed by many authors over the years, but evidence is sparse and often includes conflicting reports. Among the therapeutic options for PCa in these patients, prostate irradiation represents a valuable alternative to surgery or other systemic therapies, as RTRs are often ineligible for these treatments. Objective: To report six cases treated at our institution between 1998 and 2017 and discuss the available literature. Methods: Patients’ characteristics were reported along with biochemical status at diagnosis, type of immunosuppressive treatment, radiation therapy technique, and dose to transplanted kidney. Results: Overall, prostate irradiation was delivered respecting the dose constraints and patients showed good tolerance with no reports of acute or late transplanted kidney injury. Conclusions: Our experience confirms that prostate radiotherapy for RTRs is feasible and effective and represents a valid option that should be considered by the multidisciplinary team

Management of prostate cancer radiotherapy during the COVID-19 pandemic: A necessary paradigm change

Purpose: To adapt the management of prostate malignancy in response to the COVID-19 pandemic. Methods: In according to the recommendations of the European Association of Urology, we have developed practical additional document on the treatment of prostate cancer. Results: Low-Risk Group Watchful Waiting should be offered to patients >75 years old, with a limited life expectancy and unfit for local treatment. In Active Surveillance (AS) patients re-biopsy, PSA evaluation and visits should be deferred for up to 6 months, preferring non-invasive multiparametric-MRI. The active treatment should be delayed for 6–12 months. Intermediate-Risk Group AS should be offered in favorable-risk patients. Short-course neoadjuvant androgen deprivation therapy (ADT) combined with ultra-hypo-fractionation radiotherapy should be used in unfavorable-risk patients. High-Risk Group Neoadjuvant ADT combined with moderate hypofractionation should be preferred. Whole-pelvis irradiation should be offered to patients with positive lymph nodes in locally advanced setting. ADT should be initiated if PSA doubling time is < 12 months in radio-recurrent patients, as well as in low priority/low volume of metastatic hormone sensitive prostate cancer. If radiotherapy cannot be delayed, hypo-fractionated regimens should be preferred. In high priority class metastatic disease, treatment with androgen receptor-targeted agents should be offered. When palliative radiotherapy for painful bone metastasis is required, single fraction of 8 Gy should be offered. Conclusions: In Covid-19 Era, the challenge should concern a correct management of the oncologic patient, reducing the risk of spreading the virus without worsening tumor prognosis

Toxicity after moderately hypofractionated versus conventionally fractionated prostate radiotherapy: A systematic review and meta-analysis of the current literature

Background: Moderately hypofractionated radiotherapy (RT) currently represents the standard RT approach for all prostate cancer (PCa) risk categories. We performed a systematic review and meta-analysis of available literature, focusing on acute and late genitourinary (GU) and gastrointestinal (GI) adverse events (AEs) of moderate hypofractionation for localized PCa. Materials and methods: Literature search was performed and two independent reviewers selected the records according to the following Population (P) Intervention (I) Comparator (C) and Outcomes (O) (PICO) question: “In patients affected by localized PCa (P), moderately hypofractionated RT (defined as a treatment schedule providing a single dose per fraction of 3–4.5 Gy) (I) can be considered equivalent to conventionally fractionated RT (C) in terms of G > 2 GI and GU acute and late adverse events (O)?”. Bias assessment was performed using Cochrane Cochrane Collaboration's Tool for Assessing Risk of Bias. Results: Thirteen records were identified and a meta-analysis was performed. Risk of acute GI and GU > 2 adverse events in the moderately hypofractionated arm was increased by 9.8 % (95 %CI 4.8 %–14.7 %; I2 = 57 %) and 1.5 % (95 % CI -1.5 %-4.4 %; I2 = 0%), respectively. Discussion: Overall, majority of trials included in our meta-analysis suggested that moderately hypofractionated RT is equivalent, in terms of GI and GU adverse events, to conventional fractionation. Pooled analysis showed a trend to increased GI toxicity after hypofractionated treatment, but this might be related to dose escalation rather than hypofractionation

Radiotherapy is effective in the management of rare penile metastases: Two case reports

Penile metastasization is an uncommon condition, mostly derived from primitive advanced abdominal cancers, with disabling symptoms. Palliative treatment, in reason of poor prognosis patients, is frequently surgical with destructive management. We report two cases of penile metastasis, from primitive prostatic adenocarcinoma and primitive urothelial carcinoma, effectively managed with radiation treatment at our institution. A three-dimensional conformal radiation therapy with 42 Gy to the planning target volume in 14 fractions was delivered. Radiation treatment was safely delivered, with low toxicity profile and achieved adequate symptoms control without compromising genitourinary functions. Radiation therapy should be considered in management of rare penile metastases
