Conformal radiotherapy (3-DCRT)

, 2009
U radu su prikazana osnovna načela i postupci važni za provođenje konformalne radioterapije. Radi se o specifičnoj radioterapijskoj metodi koja se sastoji od dva sistema: jedan čine CT-simulator i računalo, a drugi služi za samo provođenje radioterapije.

Sustainable plant‐leaf‐derived carbon dots with deep‐red emission enable 1‐min photodynamic therapy of tumors

FlexMat, EarlyView.
In this study, plant‐derived carbon dots (CDs) were prepared using natural plant leaves as raw materials through solvothermal method. These CDs retain the porphyrin structure from chlorophyll and can simultaneously generate I and II types of reactive oxygen species. A 660 nm laser irradiation for only 1 min can achieve efficient photodynamic anti‐tumor

Longitudinal Swallowing and Salivary Changes With CLR 131 and Re‐Irradiation in Recurrent Head and Neck Cancer

Head &Neck, EarlyView.
ABSTRACT Background Patients with recurrent head and neck cancer (HNC) often present with severe, persistent dysphagia and xerostomia following prior chemoradiation. Although swallowing impairments and salivary dysfunction have been reported in this population, prior longitudinal studies have not examined changes in salivary composition or how these ...

Pattern of Failure in Nasopharyngeal Carcinoma After Radiotherapy in a Low‐Incidence Population: A DAHANCA Study

Head &Neck, EarlyView.
ABSTRACT Background Nasopharyngeal carcinoma (NPC) is uncommon in many populations. Most existing clinical evidence comes from endemic areas, where Epstein–Barr virus (EBV)‐associated subtypes predominate. We analyzed patterns of failure in a population‐based cohort from Denmark, a low‐incidence setting.

Second Breast‐Conserving Treatment for Ipsilateral Breast Tumor Recurrence: A Review of Patient Selection, Reirradiation Techniques, and Clinical Outcomes

International Journal of Cancer, EarlyView.
ABSTRACT Local recurrence after primary breast cancer treatment remains a complex clinical scenario in patients previously treated with breast‐conserving therapy and radiotherapy. For decades, salvage mastectomy was considered the standard treatment for ipsilateral breast tumor recurrence, largely because of concerns about local control after repeat ...

Pretreatment EBV‐DNA/TLG‐Based Risk Stratification Is Associated With Survival Outcomes in Nonmetastatic Nasopharyngeal Carcinoma: An Exploratory Study

International Journal of Cancer, EarlyView.
ABSTRACT Whether combining pretreatment plasma Epstein–Barr virus DNA (EBV‐DNA) with 18F‐FDG PET/CT‐derived total lesion glycolysis (TLG) improves prognostic stratification in nonmetastatic nasopharyngeal carcinoma (NPC) is unclear, particularly in nonendemic populations.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Comparison of Continuous‐Time Random Walk and Fractional Order Calculus Diffusion Models for Preoperative Breast Lesion Characterization: Diagnosis, Biomarker Prediction and Molecular Subtyping

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Accurate preoperative characterization of breast lesions is important for individualized management. The conventional monoexponential (Mono) model has limited ability to capture the complex microstructure of lesions. Non‐Gaussian diffusion models, including continuous‐time random walk (CTRW) and fractional‐order calculus (FROC), may

3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.

StrataXRT Versus Mepitel Film for Prevention of Acute Radiation Dermatitis in Postmastectomy Radiotherapy: A Pooled Analysis of Intra‐Patient Randomised Trials

Journal of Medical Radiation Sciences, EarlyView.
In 120 patients receiving postmastectomy radiotherapy, each irradiated chest wall was divided into medial and lateral halves, which were randomised to Mepitel Film or StrataXRT. Mepitel Film reduced grade 2–3 acute radiation dermatitis and clinician‐assessed erythema and moist desquamation over time.
