Human papilloma virus positive (HPV+) tumors represent a large proportion of anal, vulvar, vaginal, cervical and head and neck squamous carcinomas (HNSCC) and late stage invasive disease is thought to originate from a premalignant state. Cyclic dinucleotides that activate STimulator of INterferon Genes (STING) have been shown to cause rapid regression of a range of advanced tumors. We aimed to investigate STING ligands as a novel treatment for papilloma. We tested therapies in a spontaneous mouse model of papilloma of the face and anogenital region that histologically resembles human HPV-associated papilloma...

Four 5,6-dimethylxanthone-4-acetic acid (D) and pyranoxanthone (P) hybrids (D-P-n) were design-synthesized based on multi-target-addressed strategy. D-P-4 was confirmed as the most active agent against HepG-2 cell line growth with an IC50 of 0.216 ± 0.031 μM. Apoptosis analysis indicated different contributions of early/late apoptosis/necrosis to cell death for both monomers, the combination (D + P in 1:1 mol ratio) and D-P-4. They all arrested more cells on S phase. Western Blot implied that D-P-4 regulated p53/MDM2 to a better healthy state...

AIMS: Growing numbers of patients with cancer are surviving after treatment with pelvic radiotherapy. We evaluated the technique of volumetric modulated arc therapy (VMAT), which delivers a decreased dose to the organs at risk. We aimed to determine outcomes of this technique in terms of patient-reported acute toxicity and late effects and correlate the frequency of gastrointestinal symptoms with the volume of bowel receiving radiation dose. MATERIALS AND METHODS: Patients who were to receive VMAT for gynaecological malignancy completed patient-reported outcomes at baseline, the end of treatment, 8 weeks and 1 year...

Radiotherapy is a key therapeutic modality used in the treatment of oral cavity and oropharyngeal cancers, whether as definitive treatment or postoperatively for those with high-risk factors after surgery. Although radiotherapy is a proven, effective treatment of cancer control, it can result in significant acute and late toxicities. Pretreatment patient education, supportive care, and posttreatment adherence to rehabilitative and preventive care can help mitigate toxicities. Advances in radiation delivery, such as through continued technological advances, or novel approaches to customizing radiation dose and volume, to maximize the therapeutic efficacy while minimizing side effects, are warranted...

BACKGROUND: Autologous hematopoietic cell transplantation (auto-HCT) is a standard therapy for relapsed classic Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL); however, long-term outcomes are not well described. METHODS: This study analyzed survival, nonrelapse mortality, late effects, and subsequent malignant neoplasms (SMNs) in 1617 patients who survived progression-free for ≥2 years after auto-HCT for cHL or DLBCL between 1990 and 2008. The median age at auto-HCT was 40 years; the median follow-up was 10...

Cancer survival has improved dramatically, and this has led to the manifestation of late side effects of multimodality therapy. Radiation (RT) to the thoracic malignancies results in unintentional irradiation of the cardiac chambers. RT-induced microvascular ischemia leads to disruption of capillary endothelial framework, and injury to differentiated myocytes results in deposition of collagen and fibrosis. Coexistence of risk factors of metabolic syndrome and preexisting atherosclerosis in addition to RT exposure results in accelerated occurrence of major coronary events...

Non-small cell lung cancer is still diagnosed at late stage due to the lack of early symptoms and methods of diagnostic prevention. In the past ten years several targeted therapies have been introduced or explored. Tyrosine kinase inhibitors and immunotherapy are currently considered the most effective and safe therapies in comparison to the non-specific cytotoxic agents. Regarding tyrosine kinase inhibitors the adverse effects have been fully explored, however; on the other hand for immunotherapy there are still several issues to be clarified...

Pancreatic ductal adenocarcinoma (PDA) is one of the major types of cancer that exhibit high mortality worldwide because of the late diagnosis and the lack of effective treatment. Immunotherapy appears to be ineffective in PDA treatment due to the existence of a unique immune-suppressive microenvironment in PDA. Gemcitabine-based therapy is still the most commonly used chemotherapy to treat PDA patients with only marginal increased survival rates. This prompted us to continue the search for more effective therapy for PDA treatment...

Purpose: Pathologic complete response to neoadjuvant chemoradiation therapy (CRT) is associated with improved outcomes for patients with locally advanced rectal cancer (LARC). Increased response rates have been reported with higher radiation doses, but these studies often lack long-term outcome and/or toxicity data. We conducted a case-control analysis of patients with LARC who underwent definitive CRT to determine the efficacy and safety of intensified treatment with a concomitant boost (CB) approach...

Pancreatic cancer is a high mortality form of cancer, with a median survival only six months. There are multiple associated risk factors associated, most importantly type 2 diabetes, obesity, pancreatitis and smoking. The relative rarity of the disease, however, has made it difficult to dissect causative risk factors, especially with related risk factors. A major unanswered question with important therapeutic implications is the effect of immunological responses on pancreatic cancer formation, with data from other cancers suggesting the potential for local immunological responses to either increase cancer development or increase cancer elimination...

BACKGROUND: Anthracycline-related heart failure is a leading cause of morbidity in survivors of adult-onset lymphoma. There is a paucity of information on screening for late-occurring preclinical disease, which, in turn, has limited guidelines for early detection and intervention. The objectives of this study were to examine the prevalence and risk of cardiac dysfunction, as measured by echocardiography (abnormal left ventricular systolic/diastolic function or strain), in lymphoma survivors who received treatment with anthracyclines and to evaluate the diagnostic yield of blood biomarkers in the asymptomatic setting...

BACKGROUND: Treatment options at third-line and beyond for patients with late-line metastatic colorectal cancer (mCRC) are limited, and outcomes are poor with best supportive care (BSC). This study investigated the cost-effectiveness of trifluridine/tipiracil and regorafenib relative to BSC alone in patients with mCRC who have been previously treated with, or are not considered candidates for, standard chemotherapies. MATERIALS AND METHODS: A partitioned survival model was constructed to assess the lifetime costs and benefits accrued by patients...

BACKGROUND: Breast-conserving therapy, involving breast-conserving surgery followed by whole-breast irradiation and optionally a boost to the tumour bed, is a standard therapeutic option for women with early-stage breast cancer. A boost to the tumour bed means that an extra dose of radiation is applied that covers the initial tumour site. The rationale for a boost of radiotherapy to the tumour bed is that (i) local recurrence occurs mostly at the site of the primary tumour because remaining microscopic tumour cells are most likely situated there; and (ii) radiation can eliminate these causative microscopic tumour cells...

In absolute terms: second cancer risks from radiotherapy of first cancers in adults are small compared to the benefits from radiotherapy but this is not so for radiotherapy of childhood cancers. Moreover, the radiation dose dependence of cancer induction differs between organs and tissues. The organ-specific dose dependence of second cancer risks may indicate the existence of different radiobiological mechanisms. As an inevitable consequence of the age dependence of organ sensitivity to second cancer induction, the organ/tissue weighting factors which have been proposed by ICRP for calculating effective dose (the dose unit Sv) and for risk estimation in the general population should not be used in medical radiation exposures...

Following stereotactic radiosurgery (SRS) for brain metastases, the median time range to develop adverse radiation effect (ARE) or radiation necrosis is 7-11 months. Similarly, the risk of local tumor recurrence following SRS is < 5% after 18 months. With improvements in systemic therapy, patients are living longer and are at risk for both late (defined as > 18 months after SRS) tumor recurrence and late ARE, which have not previously been well described. An IRB-approved, retrospective review identified patients treated with SRS who developed new MRI contrast enhancement > 18 months following SRS...

Two-drug combination chemotherapy, often including cisplatin and one other drug, remains the standard of care for patients with advanced non-small cell lung cancer (NSCLC). To improve the treatment of late-stage NSCLC and decrease the toxicity of combination chemotherapy, the search for novel drugs remains vigorous. Ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic acid (5F), a bioactive compound isolated from the herb Pteris semipinnata L., has previously been shown to induce apoptosis and inhibit proliferation in various cancer cells...

BACKGROUND: Immune checkpoint inhibitors are novel agents approved for the treatment of late-stage malignancies. Despite its important clinical benefits, checkpoint inhibition is associated with a unique spectrum of side effects known as immune-related adverse events. Skin toxicities are the most frequent immune-related adverse events during anti-PD1 blockade therapies. Among them, rare cases of psoriasis exacerbation have been reported. METHODS: We present the clinical characteristics of exacerbated psoriasis in 5 patients under anti-PD1/PDL1 therapy...

BACKGROUND: In cancer follow-up, in addition to the evaluation of survival probabilities, there is a fundamental need of assessing recurrence dynamics for optimal disease management. Although the time-dependent effect of the oestrogen receptor (ER) status of the tumour has already been described, so far no factor has proven to disentangle the multi-peak behaviour observed for breast cancer recurrences. Here, we aimed at investigating whether adiposity at diagnosis, reflected by increased patient's body mass index (BMI), could be associated with breast cancer recurrence patterns over time after primary cancer therapy...

BACKGROUND: This study underscores the importance of the survivor/parent dynamic in understanding the knowledge level of childhood cancer survivors and their parents with regard to cancer diagnosis, treatments, and potential late effects, and to assess the impact of parental knowledge on survivor's knowledge. PROCEDURE: A convenience sample (N = 219 dyads) consisting of childhood cancer survivors with a parent match was used. Survivors 2 years out from completion of therapy, aged 16 to 25 years, and fluent in English or Spanish completed 2 questionnaires to assess adolescent and young adult and parental knowledge regarding diagnosis, treatment, and long-term risks...
