Why does chemotherapy cause hair loss?

cancer patient
The sight of a cancer patient covering their hair loss is all too familiar.

Hair loss is a frequent side effect of cancer treatment, and for many patients, it becomes a real worry.

Chemotherapy agents actively target and kill rapidly growing cells, such as those in a tumor. But similar to a tumor, the hair follicle is a highly active structure with a host of cells that frequently divide to produce the growing hair.

Because many chemotherapy drugs are designed to effectively kill all rapidly dividing cells, hair is the unfortunate bystander that takes the fall along with the cancer cells.

While some find the thought of losing their hair so distressing that they refuse chemotherapy, most people will see their locks grow back after the treatment has finished.

Chemotherapy-induced hair loss

The level of hair loss, or chemotherapy-induced alopecia (CIA), depends on the type of cancer, the specific drug, and the dose and pattern of the treatment.

Many patients experience the first wave of CIA within 1 to 2 weeks of starting their treatment.

Areas that experience high friction during sleep, such as the top of the head and the sides above the ears, are often the first to see hair loss. Yet the precise pattern depends on the individual’s hair.

Those hairs that are actively growing will be most affected, but because growing hair follicles can be arranged in patches or evenly distributed all over the scalp, it is unfortunately impossible to predict the pattern of hair loss for any given individual.

By 3 months, hair loss is often complete.

Hair regrowth after chemotherapy usually starts within 1 to 3 months after the therapy has finished. Up to 60 percent of patients report a change in hair color or structure during the first wave of hair regrowth, with many experiencing curlier hair. However, these changes are mostly temporary, and hair returns to normal eventually.

The impact of hair loss

Hair has important functions in culture and communication, and so CIA is consistently ranked top of the list of traumatic events for many patients that undergo chemotherapy.

Some patients even consider refusing chemotherapy as a result of the impending threat of CIA.

Treatments for CIA are, at best, experimental. Cooling the scalp with ice packs or special caps was first introduced in the 1970s.

The theory underlying this treatment is that cooling will narrow the blood vessels leading to the hair follicles. Some studies have reported success rates of up to 50 percent with this technique, but there is clearly a need for more effective therapies.

On the hunt for new drug targets

Very little is known about how chemotherapy drugs cause CIA. Most information stems from studies using mouse models.

Here, research has shown that programmed cell suicide, or apoptosis, is the most likely cause of cell death in the hair follicle, causing the hair to fall out.

Researchers in the Department of Medicine at the University of Chicago, IL, used genome-wide association studies to compare the genetic signature of breast cancer patients who had experienced CIA with that of those who had not.

They found several candidate genes that might be implicated in the loss of functional hair follicles. One of these, CACNB4, is part of a calcium channel that plays an important role in cell growth and apoptosis. Another gene, BCL9, was active in a subset of CIA patients and is known to play a role in hair follicle development.

Armed with this knowledge, scientists are continuing their quest to develop effective inhibitors of chemotherapy-induced hair loss, hoping to reduce the burden that this unwanted side effect has on cancer patients.

Effects of Childhood Cancer on Parents’ Relationship

Effects of Childhood Cancer on Parents’ Relationship

Parents who are dealing with caring for a Child with Cancer undergo huge amounts of stress, and generally experience both positive and negative changes in their relationships, communication, stress, and their roles.

Emotions run the gamut; anger, anxiety, guilt, and distress will all ebb and flow during the course of the child’s illness. Childhood cancer is a family affair, and while these emotions will generally all be expressed at one time or another by all family members, expression is generally more overt from mothers and children.

Childhood Cancer affects the family’s needs in a myriad of ways such as self-esteem, social interaction, their need for care, and general functioning. This may cause the parents to have to change or modify their family roles to cope with the demands of their child’s illness.

The ways in which having a Child with Cancer affects the fathers’ and mothers’ relationships vary from family to family; in some cases the stress of coping with the disease will weaken the relationship while in others the cancer experience strengthens the relationship.

According to extensive research with parents of children diagnosed with cancer, time since diagnosis is an important factor in the couple’s relationship:

  • Many of the changes occur shortly after diagnosis;
  • When the child has been ill for 1 year, there were fewer changes in parents’ relationships;
  • After 2 or 3 years, many couples experience positive changes;
  • After 4 years or more, most parents note little to no additional changes;
  • During times of remission, family life generally returns to normal, and there is a sense of a strengthened relationship between the parents;
  • Should the child’s cancer relapse however, the entire crisis process can be re-established, and this can either lead to a greater emotional closeness or magnify strengths and weaknesses of the marriage.

Childhood Cancer calls for parents to invest, at least for a time, the majority of their physical and emotional energy in their child’s illness. This can leave minimal time for intimacy and leisure activities, and high stress factors can lead to negative changes in couples’ intimate relationships. The mother, who is generally the main caregiver, could begin to feel that the adverse and stressful circumstances generated by their child’s cancer are weakening the connection with their partner.

Each spouse deals with their sick child in his or her own way and may sometimes feel that they cannot meet the other parent’s needs. This can also lead to difficulties in communication, conflicts, and lack of alignment between parents that could interfere with providing optimal care for their child with cancer.

Mothers may expect fathers to help when they feel overwhelmed with caring for their Child with Cancer as well as managing the daily family routine and their own jobs, as well. Many mothers end up having to give up their jobs in order to care for their child, and although this may give them more time to spend with their ill child, it also adds more physical, emotional and financial stress.

Fathers on the other hand may feel burdened by their jobs and may want or need to just relax quietly at home after work. Fathers may also find it difficult to acknowledge their weaknesses and vulnerabilities, and may repress their fear and inner conflict because that is what they perceive society requires of them. Unfortunately this may also lead to them “being strong” for their wives, and not sharing their feelings with them, which could lead to schisms developing in the marriage relationship.

Mothers may find that during their child’s illness, their role as wife may be totally replaced by the caregiver role. Fathers who were not normally directly involved in household tasks before may have to start assuming these roles, even if they have a full-time job.  In times of crisis, mothers generally focus on involvement in the child’s life by being physically present, while fathers advocate for and support their children and their wife.

It is vital that both parents are comfortable and flexible in dealing with these role changes by emphasising the importance of working together in a partnership, as a team, independently of how roles are shared.  Conflicting needs of both spouses must be reconciled through communication and negotiation, as they are both equally valid and heartfelt.

It is important that both partners remain emotionally available for each other, whether separated or together; both parents will suffer when they do not have the other’s emotional support, but their bond is strengthened when they share their feelings.

If you are a parent of a Child with Cancer and notice that there are stresses and tensions that seem to be splitting you and your partner, you should seek professional assistance – your child’s oncology team can usually provide you with some form of assistance or at least a referral to a counsellor.

(CNN)This 7-year-old’s last-day-of-school photo is melting hearts for more than that adorable smile.

When Sophi Eber began kindergarten, she was in the fight of her young life with stage IV neuroblastoma. On her very first day, her mother snapped a photo of her baby beaming, despite the uncomfortable accessories that come with cancer treatment.
Six rounds of chemo, 14 rounds of radiation, one nine-hour surgery and immune system stimulants later, Sophi’s done with her first year of school, and with cancer.
Mom Bethany Eber said she posted the end-of-year photo as a way to offer encouragement to other families like hers.
“When you are in those trenches, it’s hard to see beyond,” she told CNN. “For these other cancer families, it was hope for their kid.”
Sophi’s chances of relapse are high. So she’ll continue with screenings and tests every three months for the next five years.
That’s not getting her down, though.
Sophi’s giddy about her new internet fame. Since her mom posted the photo on Reddit, it’s received more than 150,000 “upvotes.”
“It feels amazing, I’ve always wanted to do this ever since I was a little kid,” Sophi told CNN affiliate WDAF about her newfound fame.
Her mom has no doubt there are big things in the future for her little girl.
“With what she’s gone through, her brain and her heart and all of the things put together, she can change the world,” her mom said. “And I fully expect her to.”
But first Sophie has the summer to get through. And she’ll do it in a very 7-year-old sort of way: at the pool.  (Read Full Story: http://www.cnn.com/2017/06/09/health/end-of-school-year-photo-trnd/index.html)

Extramedullary leukemia in children with acute myeloid leukemia: A population-based cohort study from the Nordic Society of Pediatric Hematology and Oncology (NOPHO)

Extramedullary leukemia in children with acute myeloid leukemia: A population-based cohort study from the Nordic Society of Pediatric Hematology and Oncology (NOPHO)

Abstract

Background

The prognostic significance of extramedullary leukemia (EML) in childhood acute myeloid leukemia is not clarified.

Procedure

This population-based study included 315 children from the NOPHO-AML 2004 trial.

Results

At diagnosis, 73 (23%) patients had EML: 39 (12%) had myeloid sarcoma, 22 (7%) had central nervous system disease, and 12 (4%) had both. EML was associated with young age (median age: 2.6 years), a high white blood cell count (median: 40 × 109/l), M5 morphology (40%), and 11q23/MLL (KMT2A) rearrangements (34%). No patient received involved field radiotherapy. Five-year event-free survival did not differ significantly between the EML and the non-EML patients (54% vs. 45%, P = 0.57), whereas 5-year overall survival (OS) was significantly lower in the EML group (64% vs. 73%, P = 0.04). The risk of induction death was significantly higher for EML patients (8% vs. 1%, P = 0.002). There was a trend toward a lower risk of relapse for EML patients (5-year cumulative incidence of relapse 33% vs. 49%, P = 0.16). Traumatic lumbar puncture did not adversely affect survival in this cohort.

Conclusions

EML was associated with increased risk of induction death impacting the OS. No patients relapsed at the primary site of the myeloid sarcoma despite management without radiotherapy.

Austin, Childhood Cancer Survivor, Perfects His Back Handspring #BraveKid

Austin, Childhood Cancer Survivor, Perfects His Back Handspring #BraveKid

In July 2007, at the age of 10 months, Austin was diagnosed with bilateral Wilms tumor, a type of childhood cancer in both kidneys. He was thrust into a world of chemotherapy, hospital stays, and four abdominal surgeries before being declared cancer free eight months later.

But after one year, the cancer was back. More chemo, radiation, and surgeries cost him his entire right kidney and half of his left.

Today, Austin is a relatively healthy, extremely happy and remarkably normal 7-year-old, despite living with stage 3 renal failure as a result of his childhood cancer treatment. He is energy is boundless, he loves gymnastics, and he has recently mastered his back handspring.

Austin is one of five St. Baldrick’s Foundation 2012 Ambassadors.

Riley’s journey with Medulloblastoma…A survivor’s story!!  #BraveKid

Riley’s journey with Medulloblastoma…A survivor’s story!! #BraveKid

UPDATE: Jan. 2015 Riley had another recurrence in July 2013. She had another craniotomy where they were able to remove 90-95% of the tumor, she then had a stem cell transplant in Oct. 2013. 6 weeks after the transplant, there was no sign of the residual tumor!! She had scans on Jan 5, 2015 and she still has No Evidence of Disease (NED)!! She is currently attending school and trying to get back to living her life like a “normal” 14 year old!!

UPDATE: July 2012 – Recurrence confirmed…completed 5 sessions of Cyber Knife treatment, waiting for Sept to have next scan to see if it worked! She continues to be positive & an inspiration to everyone that knows her!!

The courage of a child is amazing and regardless of the struggles she faced, how she always kept a smile on her face!! SHE IS MY HERO!! This is a glimpse into my daughter Riley’s battle with cancer. In 2008, when she was 7, she was diagnosed with Medulloblastoma – a malignant brain tumor. We almost lost her in Feb 2009 when she went into septic shock after contracting Pneumonia. She is still facing many obstacles from the effects of her treatment but she is still alive and still CANCER FREE!!!
