Randomized trial on acute toxicities of weekly vs three-weekly cisplatin-based chemoradiation in head and neck cancer

A Critical Review on the Role of Probiotics in Lung Cancer Biology and Prognosis

Lung cancer remains the leading cause of cancer-related deaths worldwide. According to the American Cancer Society (ACS), it ranks as the second most prevalent type of cancer globally. Recent findings have highlighted bidirectional gut-lung interactions, known as the gut-lung axis, in the pathophysiology of lung cancer. Probiotics are live microorganisms that boost host immunity when consumed adequately. The immunoregulatory mechanisms of probiotics are thought to operate through the generation of various metabolites that impact both the gut and distant organs (e.g., the lungs) through blood. Several randomized controlled trials have highlighted the pivotal role of probiotics in gut health especially for the prevention and treatment of malignancies, with a specific emphasis on lung cancer. Current research indicates that probiotic supplementation positively affects patients, leading to a suppression in cancer symptoms and a shortened disease course. While clinical trials validate the therapeutic benefits of probiotics, their precise mechanism of action remains unclear. This narrative review aims to provide a comprehensive overview of the present landscape of probiotics in the management of lung cancer.

Effects of intensity-modulated radiotherapy combined with chemotherapy and prognostic factors in patients with locally advanced oesophageal cancer

PURPOSE

We explored the efficacy and influencing factors of chemoradiotherapy and radiotherapy alone in patients with locally advanced oesophageal squamous cell carcinoma.

METHODS

We retrospectively analysed 226 locally advanced oesophageal squamous cell carcinoma patients who underwent chemoradiotherapy and radiotherapy alone. Univariate and multivariate Cox regression analyses were used to analyse the impact of relevant factors. The endpoint was overall survival and progression-free survival.

RESULTS

Compared with the radiotherapy group, the chemoradiotherapy group had a significant difference in the overall survival rate and the progression-free survival rate between 3 and 5 years (both p ​< ​0.05). The incidences of radiation pneumonitis and radiation oesophagitis were analysed, and the differences were not significant (all p ​> ​0.05). The incidence of haematological toxicity in the chemoradiotherapy group was significantly higher than that in the radiotherapy group (p ​= ​0.001). There was a significant difference in the incidence of haematological toxicity between the ≤65 and the >65 age groups (p ​< ​0.05). Tumour location, T stage, tumour length, tumour target volume, and short-term curative effect were the main factors affecting the prognosis (all p ​< ​0.05). T stage, gross tumour volume, and short-term curative effect were all independent factors affecting the prognosis (all p ​< ​0.05).

CONCLUSIONS

Patients with locally advanced oesophageal cancer who received intensity-modulated radiotherapy (IMRT) combined with chemotherapy had significant survival benefits compared with radiotherapy alone. Haematological toxicity was the main adverse reaction. T-stage, gross tumour volume and short-term curative effect were independent factors influencing the prognosis.

Expectations and Experiences of Participating in a Supervised and Home-Based Physical Exercise Intervention in Patients with Head and Neck Cancer during Chemoradiotherapy: A Qualitative Study

(1) Background: Chemoradiotherapy (CRT) for head and neck cancer (HNC) is associated with severe toxicity resulting in fatigue and weight loss, including loss of skeletal muscle mass. Exercise interventions might positively affect physical fitness and quality of life. Sufficient adherence and compliance rates are necessary for optimal effects. This study aimed to gain insight into expectations and experiences and factors influencing adherence, retention and compliance of HNC patients participating in exercise intervention during CRT. (2) Methods: Consecutive participants were invited for semi-structured interviews, conducted pre- and post-intervention. A deductive approach was used to identify themes and factors influencing adherence, retention and compliance. (3) Results: Thematic saturation was reached after interviewing 14 patients pre-intervention. Five themes were identified: planning and time management, treatment toxicity, motivation to exercise, exercise intervention and supervision by a physiotherapist. The intensity of the treatment schedule and treatment toxicity were important barriers. Facilitators mentioned were physical and emotional benefits, social support as well as the simplicity and home-based setting of the intervention. (4) Conclusions: A personalised approach, considering the individual facilitators and barriers of HNC patients, is important to increase adherence, retention and compliance to exercise intervention and to reap the optimal effects of the program.

Sumac-rose water mouthwash versus benzydamine to prevent radiation-induced oral mucositis in head and neck cancers: a phase II randomized trial

BACKGROUND

Radiation-induced oral mucositis (OM) largely impairs the quality of life (QoL) of patients with head and neck cancer (HNC). Few choices with limited efficacy are available to prevent this adverse effect. This randomized trial was conducted to compare the efficacy of benzydamine (standard) and a new combination (sumac and rose water) in preventing radiation-induced OM.

METHODS

This was a phase II, triple-blind, active-controlled, randomized trial. The primary endpoint was OM, and the secondary endpoints were oral pain and QoL. Besides, the possible variables defining the outcomes were analyzed using the chi-squared test (univariate analysis) and binomial regression model (multivariate analysis).

RESULTS

Sumac-rose group had fewer high-grade OM (33% vs. 63%, odds ratio [OR] 0.28, 95% confidence interval [CI 95%] 0.08-0.93, P = 0.03) and better QoL (P < 0.05). Multivariate analysis confirmed these findings. Sumac-rose rinsing could also postpone the start of oral pain (hazard ratio [HR] 0.02, CI 95% 0.001-0.32, P = 0.001) and high-grade OM (HR 0.28, P = 0.03) compared with benzydamine.

CONCLUSIONS

The sumac-rose group had a lower OM rate and grade and higher QoL than the benzydamine group. In addition, the experimental group developed high-grade OM and oral pain later during the radiotherapy course. Further studies need to be conducted to assess the role of sumac and rose water in reducing grade 3-4 mucositis in patients who undergo chemoradiation for head and neck cancer.

Acute Kidney Injury after Multiple Cycles of Cisplatin Chemotherapy: A Nomogram for Risk Assessment

INTRODUCTION

Acute kidney injury (AKI) caused by cisplatin is common and has a higher incidence of multiple use, resulting in a poor short- and long-term prognosis for patients. There is currently no good premedication AKI risk assessment tool. The aim of this study was to establish an AKI risk assessment nomogram for patients with multiple cisplatin applications.

METHODS

This study was a retrospective analysis of patients who were treated with non-first-time cisplatin chemotherapy regimen at Changzhou Second People's Hospital affiliated to Nanjing Medical University from January 2016 to January 2022. All data from the development group were used to screen the impact factors of AKI via univariate and multivariate analyses. A nomogram was developed based on these impact factors and verified with verification group. The area under the curve (AUC) of receiver operating characteristic (ROC) curve, calibration curves, and decision curve analyses (DCAs) were used to evaluate the nomogram.

RESULTS

Among the 256 patients enrolled in 450 cycles of chemotherapy, 282 were in the development cohort (97 AKI), and 168 were in the validation cohort (61 AKI). Multivariate logistic regression revealed that age, hypertension, diabetes, serum cystatin C (sCysC), urinary kidney injury molecule-1 (uKim1), and a single dose of cisplatin were independently associated with AKI. The results showed that our model yielded satisfied diagnostic performance with an AUC value of 0.887 and 0.906 using the development group and on verification group. The calibration plots and DCA showed the superior clinical applicability of the nomogram. These results were verified in the validation cohort.

CONCLUSION

A nomogram combining functional (sCysC) and tubular (uKim1) injury biomarkers with conventional clinical factors might assess the risk of AKI after multiple cycles of cisplatin chemotherapy.

Nonsurgical Treatment Strategies for Elderly Head and Neck Cancer Patients: An Emerging Subject Worldwide

Consistent with the increasing rate of head and neck cancers among elderly adults, there has been an increase in the rate of those receiving nonsurgical treatments to maintain their function and quality of life. However, various problems, such as poor tolerance to chemoradiotherapy-related toxicity, are of greater concern in elderly adults than in younger individuals. In this review, we describe adverse events that should be particularly noted in elderly patients and provide an overview of countermeasures in nonsurgical treatments. We mainly focus on cisplatin-based chemoradiotherapy-the primary treatment for head and neck squamous cell carcinoma (HNSCC). Furthermore, we review the molecular targeted drugs and immune checkpoint inhibitors for elderly patients with HNSCC. Although the number of older patients is increasing worldwide, clinical trials aimed at determining the standard of care typically enroll younger or well-conditioned elderly patients. There is still very little evidence for treating elderly HNSCC older patients, and the question of optimal treatment needs to be explored.

A novel biocompatible Eu-based coordination polymers of cytarabine anticancer drug: Preparation, luminescence properties and in vitro anticancer activity studies

In this study, we use cytarabine anticancer drug to synthesize a new rare earth complex with Europium ion. The study work is an attempt to investigate luminescence and biological properties of the Eu-based coordination polymers of cytarabine (Eu-CP-Ara) anticancer drug which have been prepared by us. Eu-CP-Ara has luminescence properties with emission centering at about 619 nm excited with 394 nm. We study cytarabine and Eu-CP-Ara in vitro cytotoxicity. Cytotoxicity of Eu-CP-Ara against lung cancer cells (A549) could even be comparable to the inhibitory effect of cytarabine ligands, showing the advantage of antitumor activity. In addition, Eu-CP-Ara showed lower cytotoxicity to normal liver cells (L02). At the same, from the CLSM images, Eu-CP-Ara has successfully entered the A549 cell. Hence, Eu-CP-Ara can be used as a potential anticancer drug. Eu-CP-Ara may be an effective strategy for the tracking cytarabine against tumours and might impart better accurate treatment effect and therapeutic efficiency.

Precision medicine for risk prediction of oral complications of cancer therapy–The example of oral mucositis in patients receiving radiation therapy for cancers of the head and neck

Oral complications of cancer therapy are common, markedly symptomatic, negatively impact patients' quality of life, and add significantly to the cost of care. Patients' risk of treatment-related toxicities is not uniform; most patients suffer at least one side effect, while others tolerate treatment without any. Understanding those factors which impact risk provides opportunities to customize cancer treatment plans to optimize tumor kill and minimize regimen-related toxicities. Oral mucositis (OM) is an iconic example of a clinically significant and common complication of head and neck radiotherapy. Individuals' OM risk is governed by the cumulative impact of factors related to treatment, the tumor, and the patient. In addition to OM risk prediction, a second opportunity to apply precision medicine will evolve as viable treatment options become available. Patients vary widely in how well or poorly they respond to specific treatments. What works well in one individual, might fail in another. Prospective determination of the likelihood of a patient's response or non-response is based on a range of biological interactions. Coupled with risk determination, the application of precision medicine will allow caregivers, patients, and payers to integrate risk/benefit to optimize the probability that the best treatment is be given to the most appropriate patients.

Three weekly versus weekly concurrent cisplatin: safety propensity score analysis on 166 head and neck cancer patients

Background

Radio-chemotherapy with CDDP is the standard for H&N squamous cell cancer. CDDP 100 mg/m²/q3 is the standard; alternative schedules are used to reduce toxicity, mostly 40 mg/m²/q1.

Methods

Patients were treated from 1/2010 to 1/2017 in two Radiation Oncology Centres. Propensity score analysis (PS) was retrospectively used to compare these two schedules.

Results

Patients analyzed were 166. Most (114/166) had 1w-CDDP while 52 had 3w-CDDP. In the 3w-CDDP group, patients were younger, with better performance status, smaller disease extent and a more common nodal involvement than in the 1w-CDDP. Acute toxicity was similar in the groups. Treatment compliance was lower in the w-CCDP. Overall survival before PS was better for female, for oropharyngeal disease and for 3w-CDDP group. After PS, survival was not related to the CDDP schedule.

Conclusions

3w-CDDP remains the standard for fit patients, weekly schedule could be safely used in selected patients.

Concurrent Chemoradiotherapy With Weekly Low-Dose Cisplatin for Japanese Patients With Head and Neck Squamous Cell Carcinoma

Background:

Concurrent chemoradiotherapy (CCRT) with tri-weekly high-dose cisplatin (HDC) is considered the standard regimen. However, due to significant toxicity, various weekly low-dose schedules have been increasingly used. We investigated the tolerability and survival of patients with head and neck squamous cell carcinoma (HNSCC) who underwent CCRT with low-dose weekly cisplatin (LDC) for Japanese population.

Methods:

A retrospective review was conducted among patients with HNSCC who were treated with CCRT/LDC in our institute. Ninety-five patients who met the criteria were enrolled in this study. We evaluated the cycle and cumulative cisplatin dose, completion rate of radiotherapy, adverse events, and survival outcome.

Results:

The mean cycles and cumulative cisplatin dose were 4.7 cycles and 187 mg/m². All patients completed planned dose of radiation without prolonged breaks. Leucopoenia was the most frequent dose-limiting factor and 44% patients developed grade 3 or 4 toxicity. The 2-year overall survival and recurrence-free survival were 93% and 74%, respectively. The significant differences of survival outcomes between the patients with total cisplatin dose (⩾200 mg and <200 mg) or among age distribution (35-55, 56-75, and ⩾76) were not observed.

Conclusions:

Concurrent chemoradiotherapy/LDC can be safely administered with acceptable toxicity and survival outcome even if the patients with higher age, lower eGFR, and so on.

Mitochondrial Superoxide Dismutase in Cisplatin-Induced Kidney Injury

Cisplatin is a chemotherapy agent commonly used to treat a wide variety of cancers. Despite the potential for both severe acute and chronic side effects, it remains a preferred therapeutic option for many malignancies due to its potent anti-tumor activity. Common cisplatin-associated side-effects include acute kidney injury (AKI) and chronic kidney disease (CKD). These renal injuries may cause delays and potentially cessation of cisplatin therapy and have long-term effects on renal function reserve. Thus, developing mechanism-based interventional strategies that minimize cisplatin-associated kidney injury without reducing efficacy would be of great benefit. In addition to its action of cross-linking DNA, cisplatin has been shown to affect mitochondrial metabolism, resulting in mitochondrially derived reactive oxygen species (ROS). Increased ROS formation in renal proximal convoluted tubule cells is associated with cisplatin-induced AKI and CKD. We review the mechanisms by which cisplatin may induce AKI and CKD and discuss the potential of mitochondrial superoxide dismutase mimetics to prevent platinum-associated nephrotoxicity.
