PROGRESS FOR TREATING AND CURING CANCER!!

The latest annual report from the American Cancer Society (ACS) surveys cancer in many years up to the present, and provides statistical data about the current status of neoplastic disease in the United States (US) [1,2].  The largest conclusion is that clinical progress against cancer definitely is being made, but further efforts are needed.

ACS cancer statistics for 2016 [1,2]! 

The new ACS report describes numbers for cancer incidence, deaths, and survival through 2015 [1,2].  These latest figures permit comparison to corresponding measurements for many previous years, and allow predictions to be made for 2016.  Several brief discussions about what these figures reveal now are available [e.g., 3-5].

The cancer death rate for men and women fell 23% in the 21 year period from 1991 to 2012 (the latest year for which complete data are available).  This progress should be  welcomed by everyone!  Death from cancer still is second to heart disease for the entire US, but in 21 states it now has become the leading cause of death due to use of new and better therapies against heart disease.  For 2016, around 1.7 million new cases of all cancers can be expected in the US, presumably due mainly to the many environmental carcinogens we all are exposed to.

Cancers of the lung, prostate, colon, and breast remain the most frequent neoplasms nationally, and result in nearly half of the cancer deaths for both genders.  The total incidence of cancer would be higher were it not for decreased smoking of tobacco products.  Despite all measures now taken for early detection, breast cancers in women are estimated to be about 29% of all new cancer cases for females in 2016.

Incidence and death rate for some cancers are decreasing [1,2]! 

New cases of several cancers now are decreasing.  Half of the decline in new cancer cases for men is caused by the reduction of reporting prostate cancer by clinicians; this is due to their recognition that the prostate specific antigen test for the presence of prostate cancer gives positive results even for those men not needing clinical treatment.  Observed decreases in new lung cancer patients are due to the increased numbers of men and women who choose not to smoke tobacco; of course, many people still smoke, and the incidence needs to be reduced much further.  The observed decrease in colon cancer is believed due to increased use of colonoscopies as an effective screening test.

Better treatments and high levels of enrollment in clinical trials is producing a progressive increase in 5-year survival rate for children with cancer.  Among children aged 1-14 years in the US, death from cancers is second only to the deaths caused by accidents.  Leukemias account for 30% of all childhood cancers, but brain cancer now is more frequent than leukemia due to more effective therapies for treating this blood cell cancer.

Is progress truly being made in fighting cancer [1-5]? 

Despite continuing complaints that too much money is spent on treating and studying this deadly disease, progress against cancer in the US clearly is being made every year.  Education, early detection, prevention, and improved therapy all contribute to decreasing the incidence and death rates, thereby raising the number of cancer survivors.

Hidden among the tables of numbers published in the new ACS report is the solid fact that for some cancer patients death now is postponed for many years due to the development and use of more effective therapeutic treatments.  Moreover, of the more than 100 different kinds of cancer, some now are being cured!  Both of these facts provide evidence that progress in cancer care indeed is being made.

Critical discussion about the value of cancer research! 

One of the most frequent complaints about spending many billions of dollars on cancer research is that this killing disease still remains without a general cure (see: “After Spending Billions Why Have Scientists Not Yet Found a Cure for Cancer?” ).  A very strong rebuttal to this complaint is given by the thrilling research success of Dr. James P. Allison (M. D. Anderson Cancer Center, Houston, Texas) (see: “A Very New Immunotherapy Wins the 2015 Lasker-DeBakey Clinical Medical Research Award!” ).  His combined laboratory, clinical, and industrial research investigations with experimental immunology discovered a new kind of treatment that cures many cases of the previously fatal cancer, malignant myeloma (see new video: “Why Don’t Our Bodies Fight Cancer for Us?” ).   This story proves that research does result in very wonderful advances in curing some cancers!

This dramatic example of research success also illustrates several important generalizations about research on cancer: (1)  progress in treating and curing cancer proceeds step-by-step and not all-at-once, (2) basic laboratory research is the major basis leading to clinical progress against cancer, and, (3) progress in curing any type of cancer is inherently slow and takes at least one decade of dedicated work, but it is pursued by determined basic and clinical researchers.

Due to advances in cancer research, a diagnosis of cancer no longer is a certain prediction of early death!  Cancer research is the biggest stimulus for clinical progress against this disease.  The President of the American Society of Clinical Oncology, Dr. Julie M. Vose, has just stated [5], “As a result of our nation’s investment in cancer research, we have made tremendous progress in prevention, chemotherapy, surgery, radiation, immunotherapy and molecularly targeted treatments.  Every cancer survivor is living proof of its progress.”

Concluding remarks! 

This 2016 ACS report [1] documents the considerable progress being made against cancer.  An increasing number of patients with certain types of cancer now even are being cured!  Cancer research does cost lots of money and typically takes many years of work, but that leads to development of good clinical progress against this disease (i.e., decreased incidence, increased survival, and outright cures)!
