Lung cancer is caused by uncontrolled rapid growth of cells in tissues. This type of cancer is most common and results in more than a million deaths  
everyear. This form of cancer is indicated by weight loss or coughing up blood or regularly going out of breath .

Lung cancer can be noticed on chest radiograph also called CT Scan. The treatment that one gets depends on the stage that one is in .Treatment of cancer  
include surgery ,chemotherapy and radiotherapy .

CLASSIFICATION

Lung cancers are classified after studying under them microscope .Classification is necessary as different type of cancer is treated differently.
Large portion of lung cancer are carcinomas – malignancies that grow from epithical cells .Lung-carcinomas are categorized into two types : non-small and  
small-cell lung carcinoma. Non-small cell lung carcinoma and small cell lung carcinoma account for 80.4% and 16.8% frequency of lung cancer, respectively .

Afatinib (BIBW 2992*) Triples Progression Free Survival in Lung Cancer Patients

Boehringer Ingelheim announced promising results from two clinical trials of its investigational cancer compound afatinib (BIBW 2992) presented at the 35th European Society for Medical Oncology (ESMO) Congress in Milan, Italy. Results from the LUX-Lung 1 trial suggest that afatinib (BIBW 2992) is highly active in late-stage patients with NSCLC1, while in the LUX-Lung 2 phase II trial afatinib demonstrated encouraging activity in advanced NSCLC patients that have a mutated EGF Receptor.

Afatinib, which is taken as a tablet, is a next generation inhibitor of the epidermal growth factor receptor (EGFR) and human epidermal receptor 2 (HER2) tyrosine kinase (TK) and unlike first generation TKIs irreversibly binds to EGFR/HER2. The compound is under development in several solid tumour types.

The LUX-Lung 1 trial (phase II b/III) compared afatinib to placebo in over 580 patients with advanced NSCLC whose disease has progressed after receiving chemotherapy and a first-generation EGFR Tyrosine Kinase Inhibitor (gefitinib or erlotinib)  results showed1:

Cancer: A Historical Perspective By Lawrence Broxmeyer MD

 

Hodgkin’s cancer under attack

When Virginia Livingston was a student at Bellevue Medical College her pathology teacher mentioned, rather disparagingly, that there was a woman pathologist at Cornell who thought Hodgkin’s disease (a form of glandular cancer) was caused by avian tuberculosis [1]. This lady had published, but no one had confirmed her findings. Afterwards, Livingston compared slides of both. In Hodgkin’s, the large multinucleated giant cells were called Reed–Sternberg cells. They were similar to the giant cells of tuberculosis, which formed to engulf the tubercle bacilli. Livingston stored away in her memory that this lady pathologist was probably right but she would have a difficult time in gaining acceptance.

 By 1931, Pathologist Elsie L’Esperance was seeing ‘acid fast’ tuberculosis-like bacteria riddling her Hodgkin’s cancer tissue samples. And that germ, once injected into guinea pigs, caused them to come down with Hodgkin’s too, fulfilling Koch’s postulates. L’Esperance brought her stained slides to former teacher and prominent Cornell cancer pathologist James Ewing. Ewing initially confirmed that her tissue slides were indeed Hodgkin’s. But when he found out that her slides came through guinea pig inoculation of the avian (fowl) tuberculosis she had found in humans with Hodgkin’s, Ewing, visibly upset, said that the slides then could not be cancer.

It betrayed his checkered history of high-placed medical politician. In 1907, you could have approached Dr. James Ewing about a cancer germ, and he would have embraced you over it. At that time, both for he and the rest of the nations medical authorities, it was not a question of whether cancer was caused by a germ, but which one. Was not it Ewing, at one time, who had proclaimed that tuberculosis followed Hodgkin’s cancer “like a shadow”?
